NoClassDefFoundError MavenResolutionFilter

[trickydicky]

I downloaded everything, mounted it in eclipse and when I build it, everything goes fine except the tests. I get the following exception:

---

In the test pom.xml version 2.0.0-alpha-1 for shrinkwrap.resolver is used and when I go and search the not found class in the maven repository, I note that MavenResolutionFilter is in jboss/shrinkwrap/resolver/api/maven/filter in stead of in jboss/shrinkwrap/resolver/api/maven, (note the difference: filter). Don't know how to resolve this. Can anybody help me?
