         * NOTE: "invoker:install" vs "appassembler:assemble": Both mojos use the artifact installer to put an artifact
         * into a repository. In the first case, the result needs to be a proper local repository that one can use for
         * local artifact resolution. In the second case, the result needs to precisely obey the path information of the
         * repository's layout to allow pointing at artifacts within the repository. Unfortunately,
         * DefaultRepositoryLayout does not correctly describe the layout of a local repository which unlike a remote
         * repository never uses timestamps in the filename of a snapshot artifact. The discrepancy gets notable when a
         * remotely resolved snapshot artifact gets passed into pathOf(). So producing a proper local artifact path
         * using DefaultRepositoryLayout requires us to enforce usage of the artifact's base version. This
         * transformation however contradicts the other use case of precisely obeying the repository's layout. The below
         * flag tries to detect which use case applies to make both plugins happy.
