Can we assume it's resolved then?
Noo it s not ...
Long path tool is the best solution for your problem. try it and solve your problem.
How do you setup the classpath?
Did you include all artifacts manually? (That must be a lot of work!)
I am using Apache Ivy to resolve the classpath in eclipse and the ant build.
With ant I get the same problem, that's why I write the classpath into the manifest of a teststarter.jar and include only that in the classpath. That helps when using ant based builds.
