Hi,
I tried to use m2eclipse on an EAR project.
When importing an EAR project as a maven project I get the following

loader constraints violated when linking

The side effect of this exception is once the error happens all others
projects importing in the same time fail.
Do you have an idea on how to avoid this exception ?
Thanks
