多個dex文件定義了Lorg/apache/commons/io/IOUtils;

Question

我遇到了一個非常愚蠢的問題。 我無法組裝我的項目。

我創建了單個項目，例如，數據庫管理，api，自定義佈局等。現在我正在嘗試將所有這些項目合併爲一個，以構建一個應用程序。

但unfortunaley它excpected，因爲我得到這個錯誤不工作：

Execution failed for task ':app:transformDexArchiveWithDexMergerForDebug'. com.android.build.api.transform.TransformException: com.android.dex.DexException: Multiple dex files define Lorg/apache/commons/io/IOUtils;

試圖解決方案：
近3小時，我瘋了找到一個解決方案，但沒有我已經找到工作。我無法從依賴關係樹中看到引用commons-io的雙引用正在發生，這些引用正在導致此錯誤。
Multidex不是這裏的問題，沒有multidex它也無法組裝。


我正在使用Android Studio 3 Beta 5

顯而易見，我錯過了。
我真的很感激你的幫助！

Answer 1

問題解決了！ 這是一個錯誤的commons-io依賴。 其原因故障可以在這裏找到：What is the difference between maven dependencies org.apache.commons:commons-io and commons-io:commons-io?

只需更換

implementation 'org.apache.commons:commons-io:1.3.2'

與

implementation 'commons-io:commons-io:1.3.2'
