Error "Invalid thread access" during Maven import

When trying to import a maven project using Eclipse 7.1 I got the following error message:

An internal error occurred during: "Importing Maven projects". Invalid thread access.

Apparently m2eclipse importing of Maven projects is not supported in Eclipse 7.1. I uninstalled Eclipse 7.1 and installed Eclipse 7.0 to fix the problem.
