[m2e-users] Cannot enable Maven on a java project

[Bjørn Willy Arntzen <Bjorn-Willy.Arntzen@xxxxxx>]

I updated my RAD 8.0.3 m2e to v1.1.0.20111108-0328 and that may have broken something.

 

On a plain java project I’m trying to enable Maven, but get this error.

 

!MESSAGE An internal error occurred during: "Enabling Maven Dependency Management".

java.lang.NullPointerException
