带有ADT23和Android 15的Robolectric的NoClassDefFoundError

我有一个Android项目，正在尝试使用JUnit，Mockito和Robolectric设置单元测试。我正在使用ADT23（这值得一提，因为我必须手动下载Eclipse JDT，如这篇文章所示：https : //stackoverflow.com/a/25519274/3519951）。以上所有内容均在Windows 7上运行。

运行测试时，我在Android View上遇到NoClassDefFoundError错误。

是的，Android导入了（平台android-15），以及我的Android项目...这是我的荣幸：

运行配置：

• 运行所选项目中的所有测试
• 测试运行器是JUnit 4
• 使用Eclipse JUnit启动器（而不是Android JUnit Test启动器）
• 在参数选项卡中，将工作目录设置为$ {workspace_loc：ApplicationLauncherActivity}，它表示我的测试项目。

这是完整的堆栈跟踪：

一个大学有一个类似的设置目前正在运行，但是除了他运行ADT 22.3之外，我们没有发现任何明显的区别。任何帮助表示赞赏，非常感谢！

编辑：我想你们中有些人可能想看一个测试课程，这是一个。您会发现其中甚至没有对Android对象的引用，因此该错误确实与Robolectric的初始化有关...
