    w.newRealm("mojo", getClass().getClassLoader());
    Strategy s = new SelfFirstStrategy(w.newRealm("scalaScript", null));
    ClassRealm rScript = s.getRealm();
    rScript.setParentClassLoader(getClass().getClassLoader());
    // rScript.importFrom("mojo", MavenProject.class.getPackage().getName());
    // rScript.importFrom("mojo", MavenSession.class.getPackage().getName());
    // rScript.importFrom("mojo", Log.class.getPackage().getName());
    rScript.importFrom("mojo", "org.apache.maven");
    // add the script directory to the classpath
    rScript.addURL(scriptDir.toURI().toURL());
    for (String string : classpath) {
