Maven Assembly Plugin jar-with-dependencies -> No Dependencies in Jar - maven

Question

The following reference mentions the descriptor Reference jar-with-dependencies. Afaik it is a predefined assembly, which includes all jar dependencies into a single big self-contained jar file. This is great if you have multiple dependencies and need to copy your project to another machine because you don't need to update/delete obsolete libraries separately.

I added the maven-assembly-plugin to my pom, and the MyTool.jar-with-dependency.jar is created. I expected that the jar contains all external dependencies, but it is the same as the normal MyTool.jar and does not contain any dependencies like apache.commons or apache.logging.
The important detail is that the dependencies scope is set to provided. Without this it works as expected. But I use the scope later on with the maven-dependency-plugin to copy all dependencies in the provided scope to a specific directory.

I use Apache Maven 2.2.1 (rdebian-14).
How can I include the dependencies from the provided scope? Or is there an other solution?
