【问题描述】：
我正在尝试让 Mockito (1.9.5 rc1) 在我的 Android 测试中工作（使用 Robotium）。为了让它在 DVM 上运行，我将 dexmaker.jar 和 dexmaker-mockito.jar (v 0.9) 放在了测试项目的类路径中。
在 Eclipse 中将以下测试作为 Android JUnit 测试运行时：
package com.stampay.pos.test;
import roboguice.RoboGuice;
import android.app.Application;
import com.jayway.android.robotium.solo.Solo;
import com.stampay.pos.activities.HomeActivity;
import com.stampay.pos.model.Consumer;
import com.stampay.pos.util.ScannerAndroid;
import static org.mockito.Mockito.*;
public class HomeActivityTest extends ActivityTest<HomeActivity> {
private Solo solo;
Application app;
public HomeActivityTest() {
super(HomeActivity.class);
}
@Override
public void setUp() throws Exception {
solo = new Solo(getInstrumentation(), getActivity());
}
@Override
public void tearDown() throws Exception {
solo.finishOpenedActivities();
RoboGuice.util.reset();
}
public void testScan() throws Exception {
ScannerAndroid scanner = (ScannerAndroid) getActivity().getScannerHelper();
Consumer mockConsumer = mock(Consumer.class);
//scanner.generateResult("consumer1");
}
}
我得到以下堆栈跟踪：

有什么建议吗？ http://code.google.com/p/dexmaker/ 和 http://code.google.com/p/mockito/wiki/ReleaseNotes 不提供任何有用的信息。
这里好像报了类似的问题：http://www.paulbutcher.com/2012/05/mockito-on-android-step-by-step/#comment-65955
更新： 使用来自https://github.com/paulbutcher/mockito-on-android/tree/master/WarehouseManagerTest/libs 的 .jar 文件一切正常，尽管他使用了基于 1.9.1 的过时 Mockito 快照
【问题讨论】：
-
我遇到了同样的问题，我正在使用 Maven 包含依赖项，但我遇到了完全相同的错误，它找不到 com.google.dexmaker.mockito.DexmakerMockMaker 类.
-
另外，我已经研究过它被 ProGuard 删除了，但我已经尝试明确保留 DexmakerMockMaker 类。
