EE4J Maven Publishing

To publish Maven artifacts and release them, you need to use the nexus-staging-maven-plugin. The plugin has been configured in the ee4j parent pom, starting with version 1.0.5. Make sure you're using at least that version:

    <parent>
        <groupId>org.eclipse.ee4j</groupId>
        <artifactId>project</artifactId>
        <version>1.0.5</version>
    </parent>

The configuration in the parent pom causes the Maven deploy operation to be done using the nexus-staging-maven-plugin instead.

I created a job to do the build and deploy to staging for JAF. The same approach should work for most simple projects.

Create a freestyle job using the usual setup with all the required configuration and security injection. Here's the script I use for the job. It can be used to build and deploy either a SNAPSHOT release or a final release. Note that it depends on the version number already having been updated if you want to deploy a final release. You could replace the simple use of "mvn deploy" with the use of the maven-release-plugin, as others have explained. The key parts of this script are the use of the nexus-staging-maven-plugin to clean up any existing staging repositories to allow this job to be run multiple times to redeploy the artifacts.

Note that I have deploy-snapshot and deploy-release profiles in my pom, largely for historical reasons. Change or remove those as appropriate. You will need to customize the Maven build and deploy commands for your project.

When the above job is used to deploy a final release to a staging repository, the deployed artifacts can be tested, and a Release Review can be started. Once the testing is complete and the Release Review is approved, a job with the following script is used to actually release the staged artifacts. This script should not need to be customized per project.
