Description
We have a project with a few sub-projects. Only one of those subprojects uses the maven-dependency-plugin, copying the jar file artifact from one of the sibling sub-projects. The dependency plugin has worked fine in another multi-project m2 buld and release when the dependency copy was only referencing projects outside the multi-project's project tree.
But in the present multi-project release, copying that sibling jar file with the dependency plugin causes the mvn release:prepare step to fail, because it can't find the released version in the release repository. It doesn't care about referencing sibling project dependencies from the regular pom dependencies, it only chokes for the dependency:copy.
Here's a diagram for the issue with three pseudo-poms. I omitted groupId's, scm, distributionManagement, and other content from the poms that were not necessary to communicate the basic issue. I've worked around this by using the antrun plugin, which is unpleasant and untidy. This seems like it might be related to MDEP-44.
