java.lang.IllegalArgumentException：已添加：Lorg/hamcrest/BaseDescription;

所以我知道，描述了簡單的情況下，錯誤當你包括JUnit 4.10頁面：java.lang.IllegalArgumentException：已添加：Lorg/hamcrest/BaseDescription;

java.lang.IllegalArgumentException: already added: Lorg/hamcrest/BaseDescription; Conversion to Dalvik format failed with error 1

不幸的是，我使用的是依賴於JUnit的庫：

COM .googlecode.json-simple：json-simple：jar：1.1.1

所以我不能添加排除。這裏是依賴關係樹：

這裏是Maven的錯誤：

我能做些什麼來避免這個問題？

我最終排除了依賴項目中的JUnit依賴項，但如果有更好的解決方案，我仍然會更喜歡。

我會離開這個開放的情況下，以更好的答案來臨。
