Major Description
The usage pages claim that the "outputType" property is available for version 2.1 of the dependency:tree goal. However, it does not work, and after downloading the source jar for version 2.1, the TreeMojo does not have an "outputType" property. I haven't examined where it got introduced, but it's there for 2.4 for sure. The documentation should be updated to reflect it's correct point of introduction.
