我试图设置Robolectric来处理针对GoogleAPI目标编译的项目，但无法使其工作。
我尝试了各种方法，并使用deckard-gradle隔离了问题：
当我下载Deckard项目时，一切正常，并且示例测试成功运行。但是，当我将gradle文件中的compilesdk设置更改为google inc.：google api:19时，在运行测试时会出现以下注释格式错误：

以下是我的设置中的一些相关片段：

我的测试班：
@Config(manifest = "./src/main/AndroidManifest.xml", emulateSdk = 18)
@RunWith(RobolectricTestRunner.class)
public class DeckardActivityRobolectricTest {
@Test
public void testSomething() throws Exception {
Activity activity = Robolectric.buildActivity(DeckardActivity.class).create().get();
assertTrue(activity != null);
}
}
我还按照robolectric上的说明将映射和支持库安装到本地maven repo中。
你知道我的设置有什么问题吗？
最佳答案
出于各种原因，我放弃了上述方法，而将我的robolectric测试保留在gradle子模块中。你可以找到一篇我写的关于为什么我要向这个方向发展的博客文章，以及一个Deckard Gradle项目的分支，它向你展示了如何here。由于Robolectric仅支持SDK18及更低版本，因此此项目还具有一个修改过的RobolectrictTestRunner，它可以强制执行此操作，而不需要注释来模拟较低版本的SDK。
