maven-release-plugin does not include shaded artifacts

Question

I am trying to release a multi module project with shaded artifacts. When I run the release:prepare then release:perform the artifacts uploaded to the Nexus repository include only the original jar and not the shaded one.

Is it possible that the Maven "release" runs before the "package" lifecycle?

The command I'm running is:

mvn release:prepare --batch-mode -Dtag=myproject-1.2.0.0000 -DreleaseVersion=1.2.0 -DdevelopmentVersion=1.2.0 -DremoteTagging=false -DsuppressCommitBeforeTag=true -Dresume=false

my parent pom.xml is:

The folder on my computer has the shaded artifact, but the artifacts in Nexus repository conatin only the original empty Jar.

Is there a way to force the release to grab the shaded jar?

Thanks, Eyal

You may try to add the tag <shadedArtifactAttached>true</shadedArtifactAttached> in your maven-shade-plugin configuration.
