Eclipse IAM Help

[Jeff Eastman]

After deleting my .m2 repository and rebuilding Mahout I now had an 
Eclipse classpath full of obsolete references to various jars. I tried 
mvn eclipse:eclipse but it fails claiming the plugin is missing. Then I 
tried installing the Eclipse IAM plugin and marking the project "Use 
Maven dependency management". That lets me browse the .pom files and the 
project structure looks more obvious than before but it zapped all the 
source directories from my classpath. If I add them back manually I have 
20k errors. Has anybody used this plugin and can help get me sorted out 
again?
