android重復的文件復制APK META-INF許可證錯誤記錄

* What went wrong:
Execution failed for task ':app:transformResourcesWithMergeJavaResForDebug'.
> com.android.build.api.transform.TransformException: com.android.builder.packaging.DuplicateFileException: Duplicate files copied in APK META-INF/LICENSE
File1: C:\AndroidStudio\Umer_Doctor\app\libs\httpmime-4.3.5.jar
File2: C:\AndroidStudio\Umer_Doctor\app\libs\httpcore-4.3.2.jar

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

 

這個是當時拋出的異常信息，很奇怪，應該是第三方包文件沖突，下面是解決方案（如果有更了解的人歡迎詳細解說下，互相學習）

packagingOptions {
        exclude 'META-INF/DEPENDENCIES.txt'
        exclude 'META-INF/LICENSE.txt'
        exclude 'META-INF/NOTICE.txt'
        exclude 'META-INF/NOTICE'
        exclude 'META-INF/LICENSE'
        exclude 'META-INF/DEPENDENCIES'
        exclude 'META-INF/notice.txt'
        exclude 'META-INF/license.txt'
        exclude 'META-INF/dependencies.txt'
        exclude 'META-INF/LGPL2.1'
    }

這個是完整的解決方案，雖然我不知道這是什么原因，估計是編譯器的問題，說不定以后as升級了不會發生，我用的是1.5版本的
