> Invoking readProjectWithDependencies for all modules takes very long time for some projects.
For example, for servicemix-3.2.1 it takes about ~300 seconds in online mode and ~90 seconds.
I ran the code under profiler, and it seems that in online mode this project is hit by  MNG-3531.
Both in online and offline mode, however, significant time is spent in DefaultBuildExtensionScanner.scanInternal(File,
MavenExecutionRequest, List, List, boolean), so I wonder if there is a way to cache extensions
somehow.
