Since version 2.7 of the plugin it is no longer possible to create Eclipse projects for Apache commons-vfs.

Steps to reproduce

1. Check out https://svn.apache.org/repos/asf/commons/proper/vfs/trunk
2. Call "mvn eclipse:clean eclipse:eclipse"

Maven stops with an error reported from the plugin. With version 2.6 it is possible to create the projects, call

mvn org.apache.maven.plugins:maven-eclipse-plugin:2.6:clean org.apache.maven.plugins:maven-eclipse-plugin:2.6:eclipse

The output for version 2.7 is:

...

While the error is technically correct and the Eclipse project produced by version 2.6 is not valid, I have still the possibility to fix the Eclipse project manually. However, since the plugin with 2.7 will not create anything, it is really worse and I am completely left alone. Therefore, it is fine to print an explicit waring on the screen, but you should nevertheless create the project and continue.
