Error: Cannot read lifecycle mapping

[Mirosllav]

Hello,

I am new to the forum and to the STS and I have one problem which I suppose is STS/Maven configuration problem. I have STS 3.0.0M3. When I create Maven project my STS create only pom.xml file and src folder, nothing more. It should create complete project (in package explorer) as I saw on the other computer. But I have in package explorer project with only these two things and there is one error message in the pom.xml file:

Cannot read lifecycle mapping metadata for artifact org.apache.maven.plugins:mav(Click for details)

When I click for details, there are no details (actually no text in that pop up at all). I tried to solve this by my own, using google, reinstall whole STS. Nothing helps. What should I do? Can you help me?

The exception indicates some kind of corrupt or invalid xml. It could be a part of your project, but more likely, one of the plugins/dependencies in your maven repo is corrupt. Try deleting your local maven repo and trying again.

It is located here:

~/.m2/repository

This may not work, but it is a good first step.
