The important difference is this will not resolve the files for the dependencies, i.e. the artifacts
            associated with a Maven project can lack a file. As such, this annotation is meant for Mojos that only
            want to analyze the set of transitive dependencies, in particular during early lifecycle phases where
            full dependency resolution might fail due to projects which haven't been built yet.

            This element specifies a directory containing the script sources of the
            project. This directory is meant to be different from the sourceDirectory, in that its
            contents will be copied to the output directory in most cases (since scripts are
            interpreted rather than compiled).
