/**
 * Interface used to locate the root directory for a given project.

 * The root locator is usually looked up from the plexus container.
 * One notable exception is the computation of the early {@code session.rootDirectory}
 * property which happens very early.  The implementation used in this case
 * will be discovered using the JDK service mechanism.

         * 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
