android - Gradle 中的 Mockwebserver 构建抛出错误

Question

我的 gradle 文件中的这个条目:

androidTestCompile ('com.squareup.okhttp:mockwebserver:2.7.0')

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了 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，retrofit 2.0 使用 okhttp3，而 okhttp3 使用 okio:1.8.0。另一方面，mockwebserver:2.7.0 使用 okhttp:2.7.0，后者使用 okio:1.6.0。那么我该如何解决呢？

这是我的 gradle 文件的“依赖项”部分中的条目:
