In the process of trying to set up a repro for another problem altogether, I accidently hit:

 An internal error occurred during: "Updating Maven Configuration".
org.eclipse.m2e.jdt.IClasspathEntryDescriptor.getClasspathEntry()Lorg/eclipse/jdt/core/IClasspathEntry; 

I'm pasting the whole repro even though it is probably non-minimal.


Reproducible: Always

Steps to Reproduce:
1. install eclipse-java-indigo-M7-macosx-cocoa-x86_64.tar.gz

  20110519-1049

2. run updates from Help

3. Created tag m2e-bugzilla-snapshot on github.com:bimargulies/m2e-code-quality.git so you can see
where this all comes from.

4. Install http://eclipse-cs.sf.net/update/
5. Install ttp://pmd.sourceforge.net/eclipse

6. installed from com.basistech.m2e.code.quality.site-0.13.0-SNAPSHOT-site.zip
  (this takes a rather a long time 'calculating requirements' and such)
7. clone http://github.com/apache/mahout (out at command level)
8. In eclipse, import/maven/existing projects for the mahout tree
9. leave all projects selected
10. 'next'
   I see 
     Packaging war (resolve later) (selected install wtp)
     maven-antrun (resolve later) (selected Do Not Execute) add to parent
     maven-jar (install mavenarchiver pomproperties)
11. Finish
12. Confirm on install mavenarchiver and WTP
13. restart
14. An internal error occurred during: "Updating Maven Configuration".
org.eclipse.m2e.jdt.IClasspathEntryDescriptor.getClasspathEntry()Lorg/eclipse/jdt/core/IClasspathEntry;
15. Now two errors:
  Description	Resource	Path	Location	Type
maven-dependency-plugin (goals "copy-dependencies", "unpack") is not supported by m2e.	pom.xml	/mahout-examples
    line 54	Maven Project Build Lifecycle Mapping Problem
maven-dependency-plugin (goals "copy-dependencies", "unpack") is not supported by m2e.	pom.xml	/mahout-utils
    line 82	Maven Project Build Lifecycle Mapping Problem

No quick fixes for exclusions.

and a warning:

 Description	Resource	Path	Location	Type
Project configuration is not up-to-date with pom.xml. Run project configuration update	mahout-taste-webapp		line 1	Maven Configuration Problem

even though I haven't edited anything.

Updating that project yields:

An internal error occurred during: "Updating Maven Configuration".
org.eclipse.m2e.jdt.IClasspathEntryDescriptor.getClasspathEntry()Lorg/eclipse/jdt/core/IClasspathEntry;
