在Android

Question

我对Andorid和Gradle不太熟悉。我在删除@Ignore注释后试图从同一个项目中运行this unit test。但我收到以下错误

java.lang.AssertionError: Compilation produced the following errors:

/SOURCE_OUTPUT/com/example/MainActivity$$Aftermath.java:6: error: cannot find symbol
import org.michaelevans.aftermath.IAftermathDelegate;
                                 ^
  symbol:   class IAftermathDelegate
  location: package org.michaelevans.aftermath
/SOURCE_OUTPUT/com/example/MainActivity$$Aftermath.java:8: error: cannot find symbol
public class MainActivity$$Aftermath<T extends com.example.MainActivity> implements IAftermathDelegate<T> {
                                                                                    ^
  symbol: class IAftermathDelegate

有人可以指出我如何解决问题吗？
