     * Consists of two projects. First is a dependency project with a snapshot
     * version, which is deployed to the url 'file:../test-repo'. Second is a
     * project that declares a dependency on the first project, and also declares
     * a repository entry pointing to the url 'file:../test-repo' (these projects
     * are in sibling directories, so this should be the same location as the
     * first project deployed to). The second project's repository declaration
     * specifies releases disabled, and snapshots enabled with an update-policy
     * of 'always', which should trigger metadata updates on each build.
     * <br />
     * This test has four parts, executed in order:
     * <ol>
     *   <li>Deploy a snapshot dependency to the test repository, then remove
     *       the dependency from the local repository.</li>
     *
     *   <li>Build a project using that dependency using offline mode, without
     *       the dependency in the local repository. This build should fail.</li>
     *
     *   <li>Build the project again without offline mode. The dependency should
     *       be downloaded from the test repository, and the build should succeed.</li>
     *
     *   <li>Build the project once more using offline mode. The dependency should
     *       exist in the local repository, so the build should still succeed.</li>
