For more de > tails see:C:\rob\comp\workspace\murmur-events\target\pmd.xml -> [Help 1] Right... one fix would be to fix those 17 PMD violations...;-) Alternatively you can remove maven-pmd-plugin from the <plugins> section of the murmur-events/pom.xml. Or you can use that same entry to configure the maven-pmd-plugin to be less strict (not sure if that's possible...?). >> > 3..

I don't think so...? To try it out, I did "rm -rf ~/.m2/repository/org/murmur" and then "mvn install" in the top dir again. That worked fine. The output is attached. I have also zipped together my banal test project so you can try it out yourself. I will email it to you.

Yep. And with the parent POM residing in the directory above the projects, this is strange. >> > 5..

If that is an option for you, then I'm sure it will be a good thing. I have only ever been allowed to set up an intranet repository...:-) You can add that repository in your top pom. >> > 7..

If you do "mvn eclipse:eclipse" on the workspace level this maven plugin will generate the eclipse project files/directories in murmur-events and murmur. The dependency from murmur to murmur-events will be a project dependency. Note that you also need to "mvn eclipse:configure-workspace" on the workspace level before starting eclipse. This will set the M2_REPO eclipse variable, pointing to your local repository. > Thinking about this, I think I will establish a sample project with > everything and just copy it over to new projects I want to create and > update the artifactId in the pom.

You can just start out with the project and verify that it builds, then add stuff and test builds and if it breaks figure out what makes it break.... Attached is the output from me doing "mvn install" on the test project.
