maven resolves dependecy but cannot find package/classes in it

I can see two things to try to solve it out.

First, if you go in your local .m2 repo, you will see if there are other versions of the lib (however, sometimes different versions can have a different name, and therefor be stored in a different folder, which does not help)

You can also check what is the ACTUAL dependency used, in your IDE, or in command line (mvn dependency:tree). You might have to exclude some transitive dependency to remain consistent. I use the Eclipse plugin for that.

Finally, when you are sure of the dependency you use, you can open the jar and see if what you expect to be there is present.

I also had the same problem. In my case all classes in the module were in test package(it was Selenium project) and dependency was set to compile. I ended up moving some classes to main package.

Well, the actual reason was that the target computer had the restricted access to the internet, so the restricted access to the maven repos. With some black magic it did not fail with some kind of 'cannot download artifact' (maybe because of manual install of some jar files). So we got the server with normal access, set it up as a mirror, configured our maven to use the mirror and that solved the problem. Thanks @Samuel for participating in my problem, but as I can see that it was not possible to determine the problem from the problem description.
