android 4.4.2找不到类,Android Studio中找不到AndroidJUnit4.class +测试失败

./gradlew app:connectedCheck

随后级输出将是：

deleteDir(/myapp/build/outputs/androidTest-results/connected) returned: true

deleteDir(/myapp/build/outputs/code-coverage/connected) returned: true

Starting 0 tests on Device - 4.4.2

Tests on Device - 4.4.2 failed: Instrumentation run failed due to 'java.lang.ClassNotFoundException'

com.android.builder.testing.ConnectedDevice > No tests found.[Device - 4.4.2] FAILED

No tests found. This usually means that your test classes are not in the form that your test runner expects (e.g. don't inherit from TestCase or lack @Test annotations).

deleteDir(/myapp/build/reports/androidTests/connected) returned: true

:app:connectedAndroidTestDebug FAILED

:app:connectedAndroidTestDebug (Thread[Task worker Thread 3,5,main]) completed. Took 16.012 secs.

POWERMOCK_VERSION = 1.5.6

ROBOLECTRIC_VERSION = 2.4

UIAUTOMATOR_VERSION = 2.1.0

Android Studio失败，因为它无法解析JUnit转轮。
