我有一个使用Google Play服务的项目，特别是地图。该项目工作正常。 build.gradle中的依赖项使用google存储库，并在声明中使用
compile 'com.google.android.gms:play-services:3.2.25'
我想使用gradle-android-test-plugin，所以我配置了它，添加了测试运行器，只用assertTrue创建了一个简单的测试（true）并用./gradlew test运行它
测试失败了，java.lang.NoClassDefFoundError：com / google / android / gms / maps / model / LatLng，我猜它在读取清单时尝试加载它失败了。这是完整的错误：

引起：java.lang.ClassNotFoundException：com.google.android.gms.maps.model.LatLng 在org.robolectric.bytecode.AsmInstrumentingClassLoader.findClass（AsmInstrumentingClassLoader.java:119） at org.robolectric.bytecode.AsmInstrumentingClassLoader.loadClass（AsmInstrumentingClassLoader.java:95） ......还有49个
我试图将google play服务依赖项添加到testCompile，但没有运气。 我做错了什么？
