Where are the eclipse plugin dependencies?
Since the eclipse platform, and other required top level Eclipse projects do not publish each plugin independently to a remote maven repository, the maven build process pulls down full distributions of these required projects, unzips them to create a “target-platform”. This is done intelligently so that the target platform is not generated on every build and only if required versions of the Eclipse projects have changed, or if the “target-platform” has been altered. Each downloaded zip distribution is placed in ~/.m2/repository/eclipse/distributions. The target platform used is located at ~/.m2/repository/eclipse/eclipse. The download URL’s are for each required distribution is specfied in the root POM as such.
