使用数据库帮助程序测试服务时，NoClassDefFoundError ShadowSQLiteConnection错误

Question

我正在尝试用Robolectric测试一项服务。碰巧服务创建了一个DB连接，检查了一些东西，然后关闭了。问题是我遇到了一个机器人错误，它找不到类。

Could not initialize class org.robolectric.shadows.ShadowSQLiteConnection
java.lang.NoClassDefFoundError: Could not initialize class org.robolectric.shadows.ShadowSQLiteConnection
at java.lang.Class.newInstance(Class.java:374)
at org.robolectric.bytecode.ShadowWrangler.createShadowFor(ShadowWrangler.java:354)

at android.database.sqlite.SQLiteConnectionPool.openConnectionLocked(SQLiteConnectionPool.java:463)
at android.database.sqlite.SQLiteConnectionPool.open(SQLiteConnectionPool.java:185) ...

我的代码是：

@Config(manifest = "../App/AndroidManifest.xml",shadows = { MyShadowSystemClock.class})
@RunWith(RobolectricTestRunner.class)
public class DataServiceTest {
    MyActivity activity;
    Context context;
    @Before
    public void setUp() throws Exception {
        ShadowLog.stream = System.out;
    }
    @Test
    public void testServiceActionReference() throws InterruptedException {
        Intent startIntent = new Intent(Robolectric.application, DataService.class);
        startIntent.setAction("GET_DATA");
        DataService service = new DataService();
        service.onCreate();
        service.onStartCommand(startIntent, 0, 42);
        service.onHandleIntent(startIntent);
           assertEquals(DataService.class.getCanonicalName(),startIntent.getComponent().getClassName());
        service.stopService(startIntent);
        service.onDestroy();
    }
}

为了防止这些错误，我缺少了什么？

运行ant时，也可以在系统输出上看到这一点：

导致原因：java.lang.RuntimeException：无法提取并加载SQLite库转换为C:\Users\someone\AppData\Local\Temp\roboelectric-libs\sqlite4java.dll

您使用的是真正的旧版本吗？这似乎就是问题所在。
