m2e-wtp currently doesn't support artifacts generated by
maven-assembly-plugin within the workspace. i.e a workspace project cannot
reference a zip classifier artifact matching another workspace project.
You basically have 2 solutions :
- force the consumers to reference the zip file directly : either disable
workspace resolution for projects consuming your zip (project > maven >
disable worskpace resolution) or delete mvn-Q-resources from your
workspace. The big drawback of that approach is you'll have to execute mvn
install on mvn-Q-resources everytime a file changes
- change mvn-Q-resources type to jar. Move all your web resources to
src/main/resources and reference :
<overlay>
<groupId>mygroup</groupId>
<artifactId>mvn-Q-resources</artifactId>
<type>jar</type>
<targetPath>/WEB-INF</targetPath>
<includes>
<include>/xsl/**</include>
</includes>
</overlay>
That solution should allow you to keep working/deploying stuff incrementally
