An internal error occurred during: "Updating Maven Dependencies"

Question

Whenever I run eclipse, I get the message:

An internal error occurred during: "Updating Maven Dependencies".
Lorg/codehaus/plexus/archiver/jar/JarArchiver;

I am running maven version 3.0.4, and I've tried to update the JarArchiver only for it to fail time and time again.

Does anyone have any ideas on what might be causing the problem? If you have a solution, that would also be incredibly helpful.

Answer 1

After closing Eclipse I removed all versions from ~/.m2/repository/org/codehaus/plexus/plexus-archiver except for the latest.

During the subsequent Eclipse startup another artifact causing an error was Maven Archiver, so I deleted old versions from ~/.m2/repository/org/apache/maven/maven-archiver as well.

After another Eclipse restart I performed Maven -> Update Project. All was well after that.
