"Unable to create Maven project from repository."

I'm currently getting this error doing Maven Site:
Unable to create Maven project from repository.
My configuration:
<url>grocery.com</url>
<distributionManagement>
<repository>
<id>grocery</id>
<url>grocery.com</url>
</repository>
</distributionManagement>
As far as I understand Maven Site, at the end of the process, it should pop a report website link and this link would work locally. So, I can use any url or do I need a specific one?
Here is the full bug report:

How do you upload a Maven artifact to Github Packages using the command line?

I am trying to upload a Maven artifact I haven't built to my Organization's GitHub package registry. I am using the deploy:deploy-file Maven plugin in order to do so. Here is the command I have been using:
mvn deploy:deploy-file
-Dfile=[THE JAR FILE]
-Durl=https://maven.pkg.github.com/[ORG]
-Dregistry=https://maven.pkg.github.com/[ORG]
-DgroupId=[GID]
-DartifactId=[ARTIFACTID]
-Dversion=[VERSION]
-DgeneratePom=false
-Dtoken=[MY GITHUB TOKEN]
As a result I am receiving 401 errors from Github.
I have made sure that:
I have sufficient permissions inside of my Organization (currently Owner).
The token i am using is valid and has the appropriated scopes: I put all of them on to test.
Also, the github package page states:
<!-- Just a single step: Deploy using a GitHub token -->
$ mvn deploy -Dregistry=https://maven.pkg.github.com/[org] -Dtoken=GH_TOKEN
Why can't I find any information in Maven documentation about registry or token parameters?
Can I upload this file to the organization's registry without any kind of XML configuration file, using only the cli?
Thanks in advance.

I had success with this:
mvn deploy:deploy-file -Dfile=./[JAR].jar
-DpomFile=./pom.xml
-DrepositoryId=github
-Durl=https://maven.pkg.github.com/[OWNER]/[REPO]
-Dtoken=GH_TOKEN
And a settings.xml in my maven home directory:
<settings>
<servers>
<server>
<id>github</id>
<username>[GITHUB USERNAME]</username>
<password>[GENERATED ACCESS TOKEN]</password>
</server>
</servers>
</settings>
And inside my POM:
...
<distributionManagement>
<repository>
<id>github</id>
<name>GitHub Packages</name>
<url>https://maven.pkg.github.com/[OWNER]/[REPO]</url>
</repository>
</distributionManagement>
...

To workaround the repo issue - since I didn't want each package to be published to a different repo, I created a repo named packages and published the packages from all the other repos to it, using the same config as in the other two answers.

Url should have a repository name as well.
In one of my projects I have this in pom.xml
<distributionManagement>
<repository>
<id>github</id>
<url>https://maven.pkg.github.com/stirante/lol-client-java-api</url>
</repository>
</distributionManagement>

Exception while trying to deploy Maven build JAR to github package registry

I am trying to deploy the Maven build JAR to Github Package Registry.
I am getting exception when I execute mvn deploy command.
I am using a simple Maven project which I want to create a component JAR and store in Github Package Registry.
The build is successful I now want to deploy this artifact to registry.
I have added the below in ~./m2/settings.xml.
Added a repository element under repositories in profile.
<repository>
<id>github</id>
<name>GitHub OWNER Apache Maven Packages</name>
<url>https://maven.pkg.github.com/swastikaa-in</url>
</repository>
<servers>
<server>
<id>github</id>
<username>swastikaa</username>
<password>my personal token from github</password>
</server>
</servers>
Also, I have added the below in Maven project's pom.xml:
<distributionManagement>
<repository>
<id>github</id>
<name>GitHub OWNER Apache Maven Packages</name>
<url>https://maven.pkg.github.com/swastikaa-in/math</url>
</repository>
</distributionManagement>
Expected:
Deployment to be successful , build artifact is deployed to Github package registry.
Actual:
Exception as below:
Caused by: org.eclipse.aether.transfer.MetadataTransferException:
Could not transfer metadata com.redjohn.tools:math:0.0.2-SNAPSHOT/maven-metadata.xml
from/to github (https://maven.pkg.github.com/swastikaa-in/math):

with status code 400
Can someone help me in resolving the issue.
I have followed the instructions provided in the below link:
https://help.github.com/en/articles/configuring-apache-maven-for-use-with-github-package-registry

I had the same problem and I found that snapshot versions don't work well. If you deploy a non snapshot version, it should work.

Inside your settings.xml file, <url>https://maven.pkg.github.com/OWNER/REPOSITORY</url> you need to make use that OWNER is replaced with your github username and REPOSITORY is replaced with the name of your project repository in github.

Not able to load maven depedency for spark-cloudant. getting Missing artifact cloudant-labs:spark-cloudant:jar:2.0.0-s_2.11

In Java I am adding below maven dependency,
<dependency>
<groupId>cloudant-labs</groupId>
<artifactId>spark-cloudant</artifactId>
<version>2.0.0-s_2.11</version>
</dependency>
but it is not loading package even in pom.xml file showing below error,
Missing artifact cloudant-labs:spark-cloudant:jar:2.0.0-s_2.11
Can anyone help me please why it is causing issue?
I am able to add another maven dependencies but particularly this is not working..

It's not in the official maven repository. (http://search.maven.org/#search%7Cga%7C1%7Cspark-cloudant)
But when you check: https://mvnrepository.com/artifact/cloudant-labs/spark-cloudant/2.0.0-s_2.11 there is note:
Note: this artifact it located at Spark Packages repository
(https://dl.bintray.com/spark-packages/maven/)
So you will need to add following to your pom.xml:
<repositories>
<repository>
<id>bintray</id>
<name>bintray.com</name>
<url>https://dl.bintray.com/spark-packages/maven/</url>
</repository>
</repositories>
EDIT:
According to https://spark.apache.org/news/new-repository-service.html
Bintray, the original repository service used for https://spark-packages.org/, is in its sunset process, and will no longer be available from May 1st. To consume artifacts from the new repository service, please replace “dl.bintray.com/spark-packages/maven” with “repos.spark-packages.org” in the Maven pom files or sbt build files in your repositories.
So this should work:
<repositories>
<repository>
<id>bintray</id>
<name>bintray.com</name>
<url>https://repos.spark-packages.org</url>
</repository>
</repositories>

Check your maven repo to verify that the file name and version matches what you've specified. Most Maven repo's give you an example of what to use, copy/paste.
ex: Sonatype Nexus is a repo that I use and they let you search and get snippets so you never have to worry about typing things wrong.

Problem deploying my project to maven repository since java.net moved from CollabNet to Project Kenai

Problem deploying my jaudiotagger project since java.net moved from CollabNet to Project Kenai
I made the following changes to pom.xml
from
<repository><id>maven2-repository.dev.java.net</id>
to
<repository><id>maven2-repository.java.net</id>
from
<repository>
<uniqueVersion>false</uniqueVersion>
<id>java.net-maven2-repository</id>
<url>java-net:/maven2-repository/trunk/repository/</url>
</repository>
to
<repository>
<uniqueVersion>false</uniqueVersion>
<id>java.net-m2-repository</id>
<url>java-net:/maven2-repository-svn/trunk/repository/</url>
</repository>
and Wagon version from
<version>1.8</version>
to
<version>1.12</version>
When I run mvn deploy it just complains:
Error retrieving previous build number for artifacts 'org:jaudiotagger:jar' repository metadata for: 'snapshot org:jaudiotagger:2.0.4-SNAPSHOT' could not be retrieved from repository: java.net-m2-repository due to an error: Connection failed:Unable to connect to https://svn.java.net/svn/maven2-repository-svn/trunk/repository
What am I doing wrong
thanks Paul
