/**
 * A crude resolver that converts a Maven artifact reference
 * into a {@link java.io.File} object.
 * 
 * <p>This approach is an interim solution for Maven projects
 * until the open feature request to add formally add artifacts
 * to a test (ARQ-66) is implementated.</p>
 *
 * <p>The testCompile goal will resolve any test dependencies and
 * put them in your local Maven repository. By the time the test
 * executes, you can be sure that the JAR files you need will be
 * in your local repository.</p>
 *
 * <p>Example usage:</p>
 * 
 * <pre>
 * WebArchive war = ShrinkWrap.create("test.war", WebArchive.class)
 *     .addLibrary(MavenArtifactResolver.resolve("commons-lang:commons-lang:2.5"));
 * </pre>
