另一方面，當運行Espresso測試時，不會發生任何錯誤

環境：

Gradle 1.10

JDK 8

Android SDK的上次更新

謝謝！

Answer 1

我也遇到了這個問題，我將在這里留下一個答案，以防它在搜索此錯誤時幫助其他人遇到這篇文章。 對我來說，Robolectric的版本（或更具體地說，它依賴的ASM版本）不適用於Java 8.從Robolectric 2.2升級到2.3為我解決了這個問題。

Answer 2

解決了。 該錯誤是由.gradle文件夾中的版本沖突引起的（gradle-1.10 vs gradle 1.11）。 刪除.gradle文件夾並重新生成gradle可以解決問題。
