Support reactor reference to other modules at compile phase

When building multiple artifacts with dependencies in the reactor it appears to be currently required that you build to the "install" phase.

This can actually be a bug - see http://developer-blog.cloudbees.com/2012/12/maven-and-hack.html
Even if not a bug, this goes against some common practices such as used in the release-plugin which attempts to test the build by running all projects to compile stage only.

In comparison the maven reactor allows for dependency resolution in Java JAR dependencies as soon as the compile phase is run. It does this by pointing the artifact file to the local class folder.

NPanday could take similar action and point the file to the local target file as soon as compile.
