MockWebServer在Gradle构建中引发错误

Question

我的gradle文件中的此项：

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.

我尝试注释掉gradle文件中的不同编译项，以找出哪个冲突，但是我找不到使用com.squareup.okio：okio的哪个。

更新：我能够通过运行获取依赖项：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，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“ dependencies”部分中的条目：

Answer 1

尝试okio排除androidTestCompile

androidTestCompile ('com.squareup.okhttp:mockwebserver:2.7.0') {
    exclude module: 'com.squareup.okio'
}
