相关疑难解决方法(0)

我正在尝试将Espresso 2添加到我的项目中(它还有很多其他依赖项),但是在尝试运行测试时我遇到了这个错误:

UNEXPECTED TOP-LEVEL EXCEPTION:
com.android.dex.DexException: Multiple dex files define Landroid/support/test/BuildConfig;
    at com.android.dx.merge.DexMerger.readSortableTypes(DexMerger.java:596)
    at com.android.dx.merge.DexMerger.getSortedTypes(DexMerger.java:554)
    at com.android.dx.merge.DexMerger.mergeClassDefs(DexMerger.java:535)
    ...

非测试版本工作正常.

有没有人有关于调试此方法的最佳方法的任何提示？

我试过跑./gradlew -q :<my_project>:dependencies,但我看不出任何明显的问题(虽然我不太了解解释它的输出):
