M2Eclipse throwing java.langg.NoClassDefFoundError when updating maving project

Question

I have a fresh install of IBM's Rational Application Developer v9.1. It is based on Eclipse 4.2.1. It uses M2E 1.4.0.

However, when I import an existing Maven project, or attempt to do a Maven->Update Configuration, it throws the following error:

I went hunting around, and found that the class in question exists in the org.codehaus.plexus.plexus-io package. I downloaded it from Maven Central (I guessed at the version and d/l'ed 2.0.6) and added the jar to my plugins/ folder, but it has not made any difference.

Just to be on the safe side, I even added it to my jre/lib folder but I still get the same error message.

How do I resolve this? The RAD installation will not allow me to uninstall M2E and install a newer version, so I'm kind of with 1.4.0.

Is there anything I can try?

@benji - no but given it is a brand new project that I am importing (nothing other than a POM and some src .java files) there is nothing to clean. Plus, I saw this as an Eclipse error rather than a project specific error. My Maven project is the simplest pom.xml (has 3 deps on Velocity, CommonsPool and JodaTime) and a single Main class. — Eric B., Dec 10 '14 at 04:10
I agree. I found eclipse to behave weird many times. I re-read your question and realized that the error happens when you import the maven project into eclipse.. so I guess clean is not related.. can you paste your pom? — benji, Dec 10 '14 at 04:17
@benji - I added the pom.xml defn. Just to be thorough, I did try to clean the project, but get the same error: "Errors running builder 'Maven Project Builder' on project 'test2'." And the same stack trace in the Error Log. I did manage to remove M2E 1.4.0 and upgrade to 1.4.1, but no added benefit. Same error messages. — Eric B., Dec 10 '14 at 04:27
@benji Fair question. Hadn't actually tried before your post, but yes - I just tried an can run `mvn package` successfully from cmd prompt — Eric B., Dec 10 '14 at 04:54
Seems like maybe it can't be accessed by m2e.. can you try to add the missing jar to MANIFEST.MF under \plugins\org.eclipse.m2e.maven.runtime\META-INF, to the end of the Bundle-ClassPath property? — benji, Dec 10 '14 at 16:30
@benji - I'm not entirely sure how to specify the path. All the entries in Bundle-ClassPath are listed as relative paths "jars/xxx.jar", etc. If I look for the files, they all point to `configuration/org.eclipse.osgi/bundles/3711/1/.cp/jars`. Should I drop my missing jar in that same path? Otherwise, what kind of path to I specify for the class path? — Eric B., Dec 10 '14 at 16:38
@benji - I tried dropping it in the jars/ folder and adding the jar to to the Bundle-ClassPath at the end, but to no avail. Still same error. — Eric B., Dec 10 '14 at 16:42
@benji - After a lot of testing, I finally found a configuration that works. Removing all m2e connectors, and installing just "Maven Integration for Eclipse" (none of the optional ones) without the m2e-wtp plugin worked. It seems as though the m2e-wtp plugin is triggering this error msg. If I install the m2e-wtp plugin, the error reappears. If I delete it, the error goes away. — Eric B., Dec 11 '14 at 16:40
