Description

I encountered the following error when running an "install" on a pom project that where one of the child modules used the "dependency:unpack" goal. I can set up a simple project structure to reproduce if necessary.

Can you try clearing your repo and see if this happens again? I don't believe it has anything directly to do with the dependency plugin. It doesn't use site at all except to generate its own site, but wouldn't be used in your build time.

I've tried that and I'm currently building you a zip that reproduces it. The dependency plugin does use "attach-descriptor" when you call the unpack goal, that's where the problem appears to arise.

Unzip the attached and run "mvn install" from the dep-problem-parent project.

I changed the site dependency in the plugin to a newer version and deployed. This should fix your problem for now, but the fact that this is occuring at all means something is wrong with maven. The plugin classpath should not affect the build classpath when executing other things.
