Most likely eclipse/m2e got confused when you ran command line build.
Make sure your development environment is setup as described in [1].
Then refresh all projects from local filesystem and run full/clean build.

In the future, please ask m2e development questions on
m2e-dev@xxxxxxxxxxx mailing list

hello folks,

i try to run my self build m2e but what i always get is this exception.

i cloned m2e-core from https://git.eclipse.org/c/m2e/m2e-core.git/.
i imported all projects into my eclipse.
i can build all projects in eclipse, also buildall.sh works fine.

then i try to run the m2e feature ... didn't work :-]

i need some information how to run a development version of m2e :)

kind regards
andreas
