I\'m developing a Java EE web project. When I try to add a dependency, this error message appears. I use Eclipse Kepler.
An internal error occurred du
In case it helps anyone, in addition to deleting .settings and .project, I had to delete .classpath and .factorypath before being able to import the project successfully into Eclipse.
I had the same problem. None of the solutions here worked. I had to completely reinstall eclipse and make a new workspace. Then it worked!
