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

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

Yes, it has. And a mvn clean install from my command line maven, worked fine.

But I found a workaround, it seems. I deleted the project (without removing the files), then I did a Import Existing Maven Project, and that worked.

Normally I just Check Out from SVN and then enables Maven Dependency Management.

I will try this on some other projects, just to check that other projects also has this 'bug' ... ?

Does your project have pom.xml?
