Assuming your code matches what's in SVN, it appears that the problem is related to a bad jar file.
See line 279 here: http://svn.apache.org/viewvc/maven/plugins/trunk/maven-eclipse-plugin/src/main/java/org/apache/maven/plugin/eclipse/InstallPluginsMojo.java?annotate=616922 There's already a catch for IOException there, perhaps it should have another catch for NPE or be a little more defensive when accessing the Manifest. Any idea what file caused the error? If you can figure it out, you should be able to check the JAR and see if it has a Manifest file or not etc and see if this is actually the problem.
