Maven + Robolectric，找不到资源？

Question

最近我在写一个Android的演示应用，使用了Robolectric进行TA测试。我可以运行项目，但是当我添加测试时，它会显示类似于这样的错误：

error message="java.lang.RuntimeException: no such directory /Users/majie/Downloads/android-sdk-macosx/platforms/android-9/data/res/values" type="java.lang.RuntimeException">java.lang.RuntimeException: java.lang.RuntimeException: no such directory /Users/majie/Downloads/android-sdk-macosx/platforms/android-9/data/res/values

at android.app.Activity.setContentView(Activity.java)
at com.cisco.jabberim.ui.WelcomeActivity.onCreate(WelcomeActivity.java:21)
at Test.FTE.WelcomeActivityTest.setUp(WelcomeActivityTest.java:28)

测试文件内容如下：

@RunWith(RobolectricTestRunner.class)
public class WelcomeActivityTest {
private WelcomeActivity mActivity;
private TextView text;

@Before
public void setUp(){
    mActivity = new WelcomeActivity();
    mActivity.onCreate(null);
    text = (TextView) mActivity.findViewById(R.id.welcome);
}

@Test
public void textIsNotNull(){
    String str = text.getText().toString();
    assertNotNull(str);
}
}

pom.xml文件如下：

我真的不知道如何解决它。我不知道为什么这个奇怪的路径是“/Users/majie/Downloads/android-sdk-macosx/platforms/android-9/data/res/values”。我也不知道在哪里设置它或如何使其正确。

你从Android SDK Manager下载了Android 9 SDK吗？ - yorkw

Answer 1

使用1.0版本的robolectric jar（而不是RC1）解决了我的问题

 <dependency>
        <groupId>com.pivotallabs</groupId>
        <artifactId>robolectric</artifactId>
        <version>1.0</version>
        <scope>test</scope>
 </dependency>

Answer 2

这是Robolectric需要 /Users/majie/Downloads/android-sdk-macosx/platforms/android-9/data/res/values，但实际上在您的计算机上不存在。

这很容易解决 只需下载android-9 sdk或复制其他sdk，如android-8，并将其重命名为android-9

然后就可以了。
