重複類MultiDex $ V14.class

在ProGuard階段，我的Android gradle build失敗，MultiDex $ V14.class（見下文）出現重複類錯誤。我明白什麼是重複的類，我知道什麼是MultiDex，但我仍不明白它是如何重複的。

問題：

我看到一個定義是multidex.jar，當然。我怎麼知道其他的定義在哪裏？
是不是ProGuard應該刪除重複的條目，而不是抱怨它們？
底部的「出了什麼問題」的描述似乎與重複的類無關。是嗎？

「出了什麼問題」引用'ParcelableIRServiceEndpoint'，這取決於你在那裏做什麼 –

@ cricket_007是的，但是這與複製的MultiDex類有什麼關係？我看了一下ParcelableIRServiceEndpoint。這是一個非常簡單的類，位於導入的jar中，不包含或定義與MultiDex相關的任何內容。 –

不確定。我只是認爲「ZLIB輸入流的意外結束」可能意味着該類中的某些東西 –

-1

兩天後，我發現這個問題，在lib..multidex 1.0.1，但依賴是1.0.0，所以才殺的lib，這是現在的工作
