Consider I have a maven plugin project and I want to publish it to Github's public maven repository called "Github Packages". I've done everything by instruction and for normal projects everything works fine out of the box. But for maven plugin projects with packaging=maven-plugin the instruction doesn't work.
In build log I see something like this:
[WARNING] Could not transfer metadata repo-name/maven-metadata.xml
from/to github (https://maven.pkg.github.com/user-name/repo-name):
Failed to transfer file:
https://maven.pkg.github.com/user-name/repo-name/group-id/maven-metadata.xml.
Return code is: 422 , ReasonPhrase:Unprocessable Entity.
It seems the maven deploy plugin needs maven-metadata.xml in the group-id's root, but can't find it and no one puts it there. How to solve this problem?
I use Apache Maven 3.3.9, and use the command:
mvn clean deploy

Unfortunately I haven't found the right answer to my question, it seems that for now it's impossible to add Maven plugins to Github Packages.
However I found a workaround which uses S3 as a repository backend, so you don't need heavyweight solutions like Nexus or JFrog. You can read this and this on how to do it.
I had the same problem 422 from server: Unprocessable Entity when publishing Maven artifacts from GitHub Actions to GitHub Packages. The reason was that the corresponding tag for the uploaded artifact didn't exist yet.
The error message may be better in this case.
If you have already uploaded the artifact to the GitHub Packages then it means you have configured everything right.
I suppose the real reason for the 422 error is that you are trying to upload the same artifact with the same version that already was uploaded. And if it is not a SNAPSHOT version then the repository should deny replacing it so it behaves correctly.
I got the same error when trying to redeploy the already deployed package:
Failed to execute goal org.apache.maven.plugins:maven-deploy-plugin:2.7:deploy (default-deploy) on project MavenPluginForGithub:
Failed to deploy artifacts: Could not transfer artifact ru.dmochalov:SampleMavenPluginForGithub:jar:1.0.3 from/to github (https://maven.pkg.github.com/dmochalov/hello-world):
Failed to transfer file: https://maven.pkg.github.com/dmochalov/hello-world/ru/dmochalov/SampleMavenPluginForGithub/1.0.3/SampleMavenPluginForGithub-1.0.3.jar.
Return code is: 422, ReasonPhrase: Unprocessable Entity. -> [Help 1]
How to fix?
Is suppose you have two options:
Increment the version <version>1.0.0</version> of the plugin from 1.0.0 to 1.0.1. Consider using 1.0.1-SNAPSHOT versions if the plugin is unstable and under development. GitHub allows redeploying artifacts with SNAPSHOT versions. So you could always redeploy it when developing.
Delete the package from the repo. You can do it only for packages in a private repository.
422 error vs 401 error
I suppose that there is not accepted specification or standardization for error codes and different repositories behave differently. For example, the Maven Central repository replies with 401 error when attempting to replace the already deployed version.
Why GitHub decided to use 422 is a mystery. There is an answer in the community forum but without proper explanation.
Here's the official github link for how to do exactly that. However, since this doesn't seem to be of much help, here's a link to a gradle forum question that should help you with this. Best of luck!
I want to add the documents of Gelly to my project, but it gives me this error:
Sources not found for: org.apache.flink:flink-gelly_2.10:1.2-SNAPSHOT
This is in my pom.xml
<dependency>
<groupId>org.apache.flink</groupId>
<artifactId>flink-gelly_2.10</artifactId>
<version>1.2-SNAPSHOT</version>
</dependency>
I tried looking for a different version of gelly to solve this issue but couldn't find any. is there any other way to get the documentation?
Apache publishes SNAPSHOT artifacts only to a dedicated Maven repository. Note that these artifacts are only meant for development purposes. They are not part of an official Apache Flink release!
You have to add the following repository configuration to your pom.xml to receive SNAPSHOT artifacts:
<repositories>
<repository>
<id>apache.snapshots</id>
<name>Apache Development Snapshot Repository</name>
<url>https://repository.apache.org/content/repositories/snapshots/</url>
<releases><enabled>false</enabled></releases>
<snapshots><enabled>true</enabled></snapshots>
</repository>
</repositories>
Alternatively, you can download the latest Flink code and build it on your local machine.
I want to add the oracle jdbc driver to my project as dependency (runtime scope) - ojdbc14.
In MVNrepository site the dependency to put in the POM is:
<dependency>
<groupId>com.oracle</groupId>
<artifactId>ojdbc14</artifactId>
<version>10.2.0.3.0</version>
</dependency>
of course this does't work as it is not in the central repository used by maven.
2 questions:
How do I find a repository (if any) that contains this artifact?
How do I add it so that Maven will use it?
How do I find a repository (if any) that contains this artifact?
Unfortunately due the binary license there is no public repository with the Oracle Driver JAR. This happens with many dependencies but is not Maven's fault. If you happen to find a public repository containing the JAR you can be sure that is illegal.
How do I add it so that Maven will use it?
Some JARs that can't be added due to license reasons have a pom entry in the Maven Central repo. Just check it out, it contains the vendor's preferred Maven info:
<groupId>com.oracle</groupId>
<artifactId>ojdbc14</artifactId>
<version>10.2.0.3.0</version>
...and the URL to download the file which in this case is
http://www.oracle.com/technology/software/tech/java/sqlj_jdbc/index.html.
Once you've downloaded the JAR just add it to your computer repository with (note I pulled the groupId, artifactId and version from the POM):
mvn install:install-file -DgroupId=com.oracle -DartifactId=ojdbc14 \
-Dversion=10.2.0.3.0 -Dpackaging=jar -Dfile=ojdbc.jar -DgeneratePom=true
The last parameter for generating a POM will save you from pom.xml warnings
If your team has a local Maven repository this guide might be helpful to upload the JAR there.
The Oracle JDBC Driver is now available in the Oracle Maven Repository (not in Central).
<dependency>
<groupId>com.oracle.jdbc</groupId>
<artifactId>ojdbc7</artifactId>
<version>12.1.0.2</version>
</dependency>
The Oracle Maven Repository requires a user registration. Instructions can be found in:
https://blogs.oracle.com/dev2dev/get-oracle-jdbc-drivers-and-ucp-from-oracle-maven-repository-without-ides
Update 2019-10-03
I noticed Spring Boot is now using the Oracle JDBC Driver from Maven Central.
<dependency>
<groupId>com.oracle.ojdbc</groupId>
<artifactId>ojdbc10</artifactId>
<version>19.3.0.0</version>
</dependency>
For Gradle users, use:
implementation 'com.oracle.ojdbc:ojdbc10:19.3.0.0'
There is no need for user registration.
Update 2020-03-02
Oracle is now publishing the drivers under the com.oracle.database group id. See Anthony Accioly answer for more information. Thanks Anthony.
Oracle JDBC Driver compatible with JDK6, JDK7, and JDK8
<dependency>
<groupId>com.oracle.database.jdbc</groupId>
<artifactId>ojdbc6</artifactId>

<dependency>
<groupId>com.oracle.database.jdbc</groupId>
<artifactId>ojdbc8</artifactId>

For whatever reason, I could not get any of the above solutions to work. (Still can't.)
What I did instead was to include the jar in my project (blech) and then create a "system" dependency for it that indicates the path to the jar. It's probably not the RIGHT way to do it, but it does work. And it eliminates the need for the other developers on the team (or the guy setting up the build server) to put the jar in their local repositories.
UPDATE: This solution works for me when I run Hibernate Tools. It does NOT appear to work for building the WAR file, however. It doesn't include the ojdbc6.jar file in the target WAR file.
1) Create a directory called "lib" in the root of your project.
2) Copy the ojdbc6.jar file there (whatever the jar is called.)
3) Create a dependency that looks something like this:
<dependency>
<groupId>com.oracle</groupId>
<artifactId>ojdbc</artifactId>
<version>14</version>
<scope>system</scope>
<systemPath>${basedir}/lib/ojdbc6.jar</systemPath> <!-- must match file name -->
</dependency>
Ugly, but works for me.
To include the files in the war file add the following to your pom
<build>
<finalName>MyAppName</finalName>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<configuration>
<webResources>
<resource>
<directory>${basedir}/src/main/java</directory>
<targetPath>WEB-INF/classes</targetPath>
<includes>
<include>**/*.properties</include>
<include>**/*.xml</include>
<include>**/*.css</include>
<include>**/*.html</include>
</includes>
</resource>
<resource>
<directory>${basedir}/lib</directory>
<targetPath>WEB-INF/lib</targetPath>
<includes>
<include>**/*.jar</include>
</includes>
</resource>
</webResources>
</configuration>
</plugin>
<plugin>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>1.6</source>
<target>1.6</target>
</configuration>
</plugin>
</plugins>
</build>
Download the jar and place it in your project src/lib. Now you can use the maven installer plugin.
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-install-plugin</artifactId>
<version>2.3.1</version>
<executions>
<execution>
<id>install-oracle-jdbc</id>
<goals>
<goal>install-file</goal>
</goals>
<phase>clean</phase>
<configuration>
<groupId>com.oracle</groupId>
<artifactId>ojdbc6</artifactId>
<version>11.2.0</version>
<packaging>jar</packaging>
<generatePom>true</generatePom>
<createChecksum>true</createChecksum>
<file>${project.basedir}/src/lib/ojdbc6.jar</file>
</configuration>
</execution>
</executions>
</plugin>
Now you only have to execute mvn clean once and the oracle lib is installed in your local maven repository.
Oracle is now exposing a maven repository at maven.oracle.com
However you need to be authenticated.
See https://blogs.oracle.com/WebLogicServer/entry/weblogic_server_and_the_oracle
According to the comments in the blog post the ojdbc driver should be available at the following coordinates:
<groupId>com.oracle.weblogic</groupId>
<artifactId>ojdbc7</artifactId>
<version>12.1.3-0-0</version>
<packaging>jar</packaging>
Try with:
<repositories>
<!-- Repository for ORACLE ojdbc6. -->
<repository>
<id>codelds</id>
<url>https://code.lds.org/nexus/content/groups/main-repo</url>
</repository>
</repositories>
<dependencies>
<dependency>
<groupId>com.oracle</groupId>
<artifactId>ojdbc6</artifactId>
<version>11.2.0.3</version>
</dependency>
</dependencies>
1. How do I find a repository (if any) that contains this artifact?
As DavidS has commented the line I quoted at the time I answered is no longer present in the current (at the time I'm writing now) OTN License Agreement agreement I linked. Consider this answer only for older version of the artifact, as the 10.2.0.3.0 and the like.
All Oracle Database JDBC Drivers are distribuited under the OTN License Agreement.
If you read the OTN License Agreement you find this license term:
You may not:
...
- distribute the programs unless accompanied with your applications;
...
so that's why you can't find the driver's jar in any public Maven Repository, because it would be distributed alone, and if it happened it would be a license violation.
Adding the dependency:
<dependency>
<groupId>com.oracle</groupId>
<artifactId>ojdbc14</artifactId>
<version>10.2.0.3.0</version>
</dependency>
(or any later version) make Maven downloads the ojdbc14-10.2.0.3.0.pom only, and in that pom you can read:
...
<licenses>
<license>
<name>Oracle Technology Network Development and Distribution License Terms</name>
<url>http://www.oracle.com/technology/software/htdocs/distlic.html</url>
</license>
</licenses>
...
which informs you about the OTN License.
2. How do I add it so that Maven will use it?
In order to make the above dependency works I agree with victor hugo who were suggesting you here to manually install the jar into your local Maven repository (the .m2 directory) by running:
mvn install:install-file -Dfile={Path_to_your_ojdbc.jar} -DgroupId=com.oracle
-DartifactId=ojdbc -Dversion=10.2.0.3.0 -Dpackaging=jar
but I want to add that the license term above doesn't limit only where you can't find the JDBC jar, but it limits where you install it too!
In fact your local Maven repository must be private and not shared because if it was shared it would be a kind of distribution in which the jar is distributed alone, even if to a little group of people into your local area network, and this represent a OTN License Agreement violation.
Moreover I think you should avoid installing the JDBC jar in your corporation repository manager (such as Artifactory or Nexus) as a single artifact because if it was installed it would be still distributed alone, even if to people in your organization only, and this represents a OTN License Agreement violation.
You can use Nexus to manage 3rd party dependencies as well as dependencies in standard maven repositories.
As of today (27, February 2020) Oracle announced that it has published all JDBC client libraries from version 11.2.0.4 (e.g. ojdbc6) to 19.3.0 (e.g. ojdbc10) on Maven Central under the group id com.oracle.database:
Example:
<dependency>
<groupId>com.oracle.database.jdbc</groupId>
<artifactId>ojdbc10</artifactId>
<version>19.3.0.0</version>
</dependency>
Up to now, its not possible to use maven repositories. I'm using ivy as dependency management tool, but also use maven2' s ibiblio repositories. And this is working for ivy:
<dependency org="oracle" name="ojdbc14" rev="10.2.0.2" conf="*->default"/>
Maven2' s dependency could be something like that:
<dependency>
<groupId>oracle</groupId>
<artifactId>ojdbc14</artifactId>
<version>10.2.0.2</version>
</dependency>
Notice that i define http://download.java.net/maven/2/ and http://mirrors.ibiblio.org/pub/mirrors/maven/mule/dependencies/maven2/[organisation]/[module]/[revision]/[artifact]-[revision].[ext] as external maven2 repos on my ivy settings.
The Oracle JDBC drivers are now available in Maven Central.
Here is the Link:
Oracle JDBC Drivers - Maven Central
Oracle developers article announcing the availability of the Oracle JDBC drivers in Maven Central:
Oracle announcing - Oracle JDBC drivers available in Maven Central
Example:
<!-- https://mvnrepository.com/artifact/com.oracle.jdbc/ojdbc10 -->
<dependency>
<groupId>com.oracle.database.jdbc</groupId>
<artifactId>ojdbc10</artifactId>
<version>19.3.0.0</version>
</dependency>
Good news everyone! Finally we can use Oracle's official repo:
https://blogs.oracle.com/dev2dev/get-oracle-jdbc-drivers-and-ucp-from-oracle-maven-repository-without-ides
In my case it works for me after adding this below version dependency(10.2.0.4). After adding this version 10.2.0.3.0 it doesn't work due to .jar file not avail in repository path.
<groupId>com.oracle</groupId>
<artifactId>ojdbc14</artifactId>
<version>10.2.0.4</version>
I ship opensource under LGPLv2 and even after several email conversations with Oracle they were unclear whether I was allowed to ship their binary JDBC driver with my distribution. The issue related to whether my license was compatible with their OTN terms so they suggested I was not permitted to ship the driver. Presumably related to this part
(b) to distribute the programs with applications you have developed to your customers provided that each such licensee agrees to license terms consistent with the terms of this Agreement
So even if you manage to publish the driver legally in your exclusive/local maven repository there is still the restriction on what you are permitted to do with that artifact. Seems absurd that even if I ship their driver in binary form along with the full OTN license file I still can't use it and must force my users to manually download the Oracle driver and drop into my library path before they can use my software.
There is one repo that provides the jar. In SBT add a resolver similar to this:
"oracle driver repo" at "http://dist.codehaus.org/mule/dependencies/maven2"
and a dependency:
"oracle" % "ojdbc14" % "10.2.0.2"
You can do the same with maven. pom.xml and jar are available (http://dist.codehaus.org/mule/dependencies/maven2/oracle/ojdbc14/10.2.0.2/).
If you are using Netbeans, goto Dependencies and manually install artifact. Locate your downloaded .jar file and its done. clean build will solve any issues.
Please try below:
<dependency>
<groupId>com.oracle.ojdbc</groupId>
<artifactId>ojdbc8</artifactId>
<version>19.3.0.0</version>
</dependency>
This worked for me like charm. I went through multiple ways but then this helped me.
Make sure you follow each step and name the XML files exactly same.
https://blogs.oracle.com/dev2dev/get-oracle-jdbc-drivers-and-ucp-from-oracle-maven-repository-without-ides
The process is a little tedious but yes it does work.
You can find a Github simple sample project for use a Oracle JDBC Driver on Maven Project here.
You can find all explication for your continous integration + a sample and run on Travis-CI.

Please do following settings to resolve the error
This repository needs to be enable for finding Oracle 10.0.3.0 dependecies (this setting needs to be done in Buildconfig.groovy
grails.project.dependency.resolver = "ivy" // or ivy
Also use following setting for compile time Oracle driver download
runtime "com.oracle:ojdbc:10.2.0.3.0"
This should solve your issue for not finding the Oracle driver for grails application

But where shall I place it? To the file called settings.ini placed in M2_HOME/conf? This file is full of comments with no any sign of repositories. So I have no idea how to do this and ask you for help
You should place that in your pom.xml - see the Maven reference on the subject:
<project xmlns="http://maven.apache.org/POM/4.0.0"...
...
<repositories>
<repository>
<id>Alfresco Maven Repository</id>
...
You will only need to tinker with the Maven config if you need to setup a mirror for the repo, eg. in case your organisation has it's own Nexus/other repo mirroring the outside "world".
Cheers,
You can place right under project. For example
<project>
....
<repositories>
<repository>
<id>spring-snapshots</id>
<url>http://repo.spring.io/libs-snapshot</url>
<snapshots>
<enabled>true</enabled>
</snapshots>
</repository>
</repositories>
</project>
In default maven will try to download all the artifacts from maven central. You can add any number of added repositories using tag given above. Alfresco is yet another open maven repository.
What are the coordinates of Berkeley DB JE 5.0.x in Maven Central (or some other repo maybe)?
The link given by Shaun Hare (Oracle's bdb download page) now holds an example Maven configuration accessing Oracle's Maven repo.
Following that example I included the bdb je by adding Oracle's repository directly. If you're using a repository manager such as Nexus, you might include the repository there instead:
<dependencies>
<dependency>
<groupId>com.sleepycat</groupId>
<artifactId>je</artifactId>
<version>5.0.58</version>
</dependency>
</dependencies>
<repositories>
<repository>

<snapshots />
</repository>
</repositories>
Edit: Repaired broken hyperlinks
See here http://www.oracle.com/technetwork/database/berkeleydb/downloads/maven-087630.html
so http://mvnrepository.com/artifact/com.sleepycat/je/4.0.92
Edit sorry wrong version I suggest
wget http://download.oracle.com/maven/com/sleepycat/je/5.0.34/je-5.0.34{.jar,.jar.md5,.jar.sha1,.pom,.pom.md5,.pom.sha1,-sources.jar,-sources.jar.md5,-sources.jar.sha1,-javadoc.jar,-javadoc.jar.md5,-javadoc.jar.sha1}
