Answer 1

The standard classloader can't find class files inside a jar that is itself inside a jar. You must add every jar to the classpath, and not nest jars.

You can publish a Maven artifact, which users of your framework can then use without having to include the dependencies yourself--your pom is enough.

If you want to create an "all-in-one" artifact, consider something like OneJar or jarjar or Maven's Shade plugin to create a jar that has no external dependencies.
