I have installed Eclipse 32 bits EE with Maven and Spring but when I create 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"
Thank you for your help

It seems to be a known problem in some version combinations of Spring-Eclipse integration.
Upgrade or downgrade.

Close the eclipse and try to run eclipse with clean flag
eclipse -clean
And now try to create or update any maven project.

I had the exact same error. I had installed m2e using "Install New Software" in Eclipse Java EE Kepler. I eventually found out that Eclipse Java EE Kepler already had a whole bunch of stuff installed already including m2e. I deleted Eclipse and then re-extracted it and then it worked fine.
