 defined the maven.multiproject.includes property in any of his properties
 files for the current project. if yes. then I'm able to find projects that
 can be offered to be opened together with the current project.
 problems with the current solution are:
 1. information is duplicate. once in POM's dependencies and once in the
 maven.multiproject.includes property.
