另一方面，当运行Espresso测试时，不会发生任何错误

环境：

Gradle 1.10

JDK 8

Android SDK的上次更新

谢谢！

Answer 1

我也遇到了这个问题，我将在这里留下一个答案，以防它在搜索此错误时帮助其他人遇到这篇文章。 对我来说，Robolectric的版本（或更具体地说，它依赖的ASM版本）不适用于Java 8.从Robolectric 2.2升级到2.3为我解决了这个问题。

Answer 2

解决了。 该错误是由.gradle文件夹中的版本冲突引起的（gradle-1.10 vs gradle 1.11）。 删除.gradle文件夹并重新生成gradle可以解决问题。
