I'm using Maven for the first time. I am trying to build "GeoTools" (http://www.geotools.org/) which has a seemingly well documented "Getting Started" page. I am using NetBeans 7.3.1. When I build my project, I get a "Build Failure" :
Failed to execute goal on project tutorial: Could not resolve dependencies for project org.geotools:tutorial:jar:0.0.1-SNAPSHOT: The following artifacts could not be resolved: org.geotools:gt-shapefile:jar:10-SNAPSHOT, org.geotools:gt-swing:jar:10-SNAPSHOT: Failure to find org.geotools:gt-shapefile:jar:10-SNAPSHOT in http://download.java.net/maven/2 was cached in the local repository, resolution will not be reattempted until the update interval of maven2-repository.dev.java.net has elapsed or updates are forced -> [Help 1]
To see the full stack trace of the errors, re-run Maven with the -e switch.
Re-run Maven using the -X switch to enable full debug logging.
I'm not really sure what that means. In my code I have several imports that are considered to not exist, though I followed the pom.xml instructions to the letter. For example:
import org.geotools.data.FileDataStore;
The above has a read underline with error saying:
package org.geotools.data does not exist
Here is my XML.

Can anyone give me some advice to get this tool running? Am I making a fundamental Maven error or could it be tool-specific? The JARs show up under "Dependencies" so I don't understand why there's a problem.
Thanks in advance.
The real answer is that the GeoTools tutorial is pernicious. So if any future stragglers come here know this: on the NetBeans tutorial (and perhaps the Eclipse tutorial which I also failed to get to work) there are steps which define how to set up the pom.xml. Follow them. However, do NOT copy and paste their full pom.xml file, there's an error in it somewhere. I merely added the dependencies and repositories and built the project - successfully.
But wait there's more. After building the project I was unable to run the Quickstart.java example they provide. It crashed because
JMapFrame.showMap(map)
only accepts a "MapContext" type, which the documentation calls "deprecated". So, I imported
org.geotools.map.MapContext
and changed
MapContent map = new MapContent();
to
MapContext map = new MapContext();
Viola, beating the system. I wish developers would actually test their tutorials!

I'm following the "R for Data Science" tutorial for using the tidyverse. Because I'm eventually going to create a data analysis program in Java using Renjin, I need to be able to use the tidyverse's packages in my Maven project in Eclipse.
I've added the following dependencies in pom.xml:
<dependencies>
<dependency>
<groupId>org.renjin</groupId>
<artifactId>renjin-script-engine</artifactId>
<version>3.5-beta76</version>
</dependency>
<dependency>
<groupId>org.renjin.cran</groupId>
<artifactId>tidyverse</artifactId>
<version>1.3.2</version>
</dependency>
</dependencies>
I'm positive that the first dependency (renjin-script-engine) works. And I'm pretty sure the second dependency works as well. But whenever I run pom.xml and use the Maven test feature, it gives me the following error (I shortened it to just the important part):
[ERROR] Failed to execute goal on project Test1: Could not resolve dependencies for project Tests:Test1:jar:0.0.1-SNAPSHOT: org.renjin.cran:tidyverse:jar:1.3.2 was not found in https://nexus.bedatadriven.com/content/groups/public/ during a previous attempt.
I'm assuming that this error means I need another repository for tidyverse. Here is my current repository, which I got from the Renjin instructions:
<repositories>
<repository>
<id>bedatadriven</id>
<name>bedatadriven public repo</name>
<url>https://nexus.bedatadriven.com/content/groups/public/</url>
</repository>
</repositories>
(here's the link to those instructions as well: http://docs.renjin.org/en/latest/library/project-setup.html#maven)
I am not sure what repository I need to add.
Thank you for reading. I am a beginner, and I really appreciate any and all help.
I would like to add the following jar
gson-extras-1.0-SNAPSHOT.jar
the jar structure is the following
looking at the manifest the version is
Manifest-Version: 1.0
the pom is the following
<repositories>
<repository>
<id>grupoicarep</id>
<url>file:///C:/stix/stix_ica/stix2/lib/</url>
</repository>
</repositories>
<dependencies>
<dependency>
<groupId>com.google.gson</groupId>
<artifactId>typeadapters</artifactId>
<version>0.1</version>
</dependency>
but it shows the following error:
Failed to execute goal on project stix2: Could not resolve dependencies for project es.grupoica:stix2:jar:0.0.1-SNAPSHOT: Failure to find com.google.gson:typeadapters:jar:0.1 in file:///C:/stix/stix_ica/stix2/lib/ was cached in the local repository, resolution will not be reattempted until the update interval of grupoicarep has elapsed or updates are forced -> [Help 1]
[ERROR]
I have tried many combinations but I am just guessing and not getting the right result
I don´t know what I am doing wrong
many thanks in advance

Use below dependency to include the jar available in the local machine to maven.
<dependency>
<groupId>groupid</groupId>
<artifactId>artifactid</artifactId>
<version>1.0</version>
<scope>system</scope>
<systemPath>${basedir}\lib\JAR_NAME.jar</systemPath>

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 have tried to set up a Maven dependency within IntelliJ, but I am not sure how the contents of this repository should be built and imported into a Java project. Could someone with more experience please advise on how this is done?
Kind regards,
L
If you want to use this project in another project, you will create a dependency to this using the dependency entry mentioned on the github readme:
<dependency>
<groupId>com.hybhub</groupId>
<artifactId>concurrent-util</artifactId>
<version>0.1</version>
</dependency>
For this, you need the artifact in your local maven repository*. For this, you need to build this project or use a reference from Maven Central (Thanks #Mark Rotteveel )
Clone the project locally, you need to build it in one of the following ways
Build it from the command line: Navigate to the project's location in your shell (bash or cmd) and run mvn install
This will build the project and add the artifact (jar) to the local .m2 repository.
Import to Intellij Idea (File -> New -> From Existing Sources). Once imported, build this project from the "Maven Projects" view.
Once you have done this, you can use this in other projects using the <dependency> entries
*For production ready apps, you may want to have a common maven repository for team your like Nexus or Artifactory and use that to maintain artifacts. You would also have a build system like Jenkins.
In the link you gave it had the dependency Maven entry for that library.
<dependency>
<groupId>com.hybhub</groupId>
<artifactId>concurrent-util</artifactId>
<version>0.1</version>
</dependency>
That entry would need to be nested into you <dependencies> tag. Like the example below.
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

I have a maven project, created using the quickstart archetype.
This is my pom.xml:
<project
xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

</dependency>
<dependency>
<groupId>log4j</groupId>
<artifactId>log4j</artifactId>
<version>1.2.17</version>
</dependency>
</dependencies>
</project>
This is what I see in Eclipse:
The fact is that in the maven .m2 repository the jar exists and is resolved by eclipse, so I'm able to import and use classes from log4j as you can see in the following screenshot.
Why does eclipse still tell me that the artifact is missing?
UPDATE
As pointed out by Juned Ahsan, it could be a repository issue. So I did browse http://www.mvnrepository.com/artifacts and it shows a 404 error: the repository doesn't exist.
I switched to the official maven repo, http://repo1.maven.org/maven2/, but the error persists.
Log4j is such a popular library and used by so many frameworks. So it must be transitively injected by maven from any other dependent jar and hence it is available for you in your classpath in eclipse.
You can generate maven dependency tree using plugin.
