Make sure that the specific class(es) you get the exceptions for really are in the jars that exist in your local repo (i.e. rule out the possibility that you got a bad jar file, failed download, or the wrong version, etc.).

Maven has some options to verify checksums (-C and -c), though I am not certain if they will be verified for dependencies that were already downloaded. This might ensure the integrity of the downloads. You could also move/delete your ~/.m2/repository dir to see if re-downloading them all fixes the issue. In maven1, I remember having some bad jars as a result of hitting ctrl-C while maven was downloading a jar.

You can look inside the dependency jars in Eclipse to verify the presence of the class(es) you got the exceptions for.

I also find JarsBrowser to be a convenient tool for this kind of thing. You don't even need to install it, just run this command to "Java WebStart" it:

  javaws http://cmarton.free.fr/jarsbrowser/jarsbrowser.jnlp

...and then point it at ~/.m2/repository. Then start to type the class file name (use slashes between the package names, as opposed to dots) that you are looking for in the Search field: org/foo/bar/fubar
