Florian Müller commented on MRELEASE-285:
-----------------------------------------
I've found an another workaround.
You could add a <optional>true</optional> to your dependency, like this:
<dependency>
<groupId>ch.swisscompagny.project</groupId>
<artifactId>web</artifactId>
<version>${project.parent.version}</version>
<classifier>classes</classifier>
<optional>true</optional>
</dependency>
It's very useful with the maven-war-plugin and the overlay feature.

> I have a multi-module project where one project produces a normal jar and a
> test-jar
> (http://maven.apache.org/plugins/maven-jar-plugin/test-jar-mojo.html).
> Another submodule has a test scoped dependency on the test-jar from the first
> submodule. For example, this is the structure and produced artifacts for a
> small sample (attached) I built to reproduce this behavior:
> release-test-jar (parent project)
> project-with-test-jar (submodule)
> => project-with-test-jar-1.0.jar
> => project-with-test-jar-1.0-tests.jar
> project-using-test-jar (submodule)
> => project-user-test-jar-1.0.jar
> When I run a 'clean install' the build succeeds. However, when I run a
> 'release:prepare' the build fails with the following error:
> 1 required artifact is missing.
