我的 gradle 文件中的这个条目：
androidTestCompile ('com.squareup.okhttp:mockwebserver:2.7.0')
正在抛出错误：
Warning:Conflict with dependency 'com.squareup.okio:okio'. Resolved versions for app (1.8.0) and test app (1.6.0) differ. See http://g.co/androidstudio/app-test-app-conflict for details.
我尝试在我的 gradle 文件中注释掉不同的编译条目以找出哪个是冲突的，但我就是找不到哪个使用 com.squareup.okio:okio。
更新：我能够通过运行获得依赖项： gradlew.bat app:dependencies > c:\tmp\output.txt
+--- com.squareup.retrofit2:retrofit:2.0.0 -> 2.1.0
| \--- com.squareup.okhttp3:okhttp:3.3.0
| \--- com.squareup.okio:okio:1.8.0
--- com.squareup.okhttp:mockwebserver:2.7.0
| +--- com.squareup.okhttp:okhttp:2.7.0
| | \--- com.squareup.okio:okio:1.6.0
如您所见，改造 2.0 使用 okhttp3，它使用 okio:1.8.0。另一方面，mockwebserver:2.7.0 使用 okhttp:2.7.0，它使用 okio:1.6.0。那么我该如何解决呢？
