Maven Error: "Updating the Maven Project"

I installed Eclipse 32 bit EE with Maven and Spring, but when I create a new project with Maven, I keep getting the following error message:

An internal error occurred during: "Updating Maven Project". loader constraint violation: loader (instance of org/eclipse/osgi/internal/baseadaptor/DefaultClassLoader) previously initiated loading for a different type with name "org/apache/maven/project/MavenProject"

thanks for the help

This seems to be a known issue in some combinations of Spring-Eclipse integration versions.

Upgrade or downgrade.

I had the same error. I installed m2e using "Install New Software" in Eclipse Java EE Kepler. In the end, I found out that Eclipse Java EE Kepler already has a whole bunch of things that are already installed, including m2e. I uninstalled Eclipse and then re-extracted it and then it worked fine.

Close the eclipse and try to launch the eclipse with a clean flag

eclipse -clean

Now try creating or updating any Maven project.
