Android studio使用第三方jar包，运行报错Error:duplicate files during packaging of APK

Error:duplicate files during packaging of APK E:\MinMin_King_Android\Anroid studiodyApp_4.0_19\build\outputs\apk\E-debug-unaligned.apk

Path in archive: META-INF/RELEASE_NOTES.txt

Origin 1: E:\MinMin_King_Android\Anroid studio\android studio workSpace\EBodyApp_4.0_19\libs\poi-3.7-20101029.jar

Origin 2: E:\MinMin_King_Android\Anroid studio\android studio workSpace\EBodyApp_4.0_19\libs\poi-scratchpad-3.7-20101029.jar

You can ignore those files in your build.gradle:

android {

packagingOptions {

exclude 'META-INF/RELEASE_NOTES.txt'

}

}

Error:Execution failed for task ':packageDebug'.

> Duplicate files copied in APK META-INF/RELEASE_NOTES.txt

File 1: E:\MinMin_King_Android\Anroid studio\android studio workSpace\EBodyApp_4.0_19\libs\poi-3.7-20101029.jar

File 2: E:\MinMin_King_Android\Anroid studio\android studio workSpace\EBodyApp_4.0_19\libs\poi-scratchpad-3.7-20101029.jar

解决方法：

在 app 下的 build.gradle 中的 android 部分增加一段配置：

packagingOptions {
        exclude 'META-INF/LICENSE'
        exclude 'META-INF/NOTICE.txt'
        exclude 'META-INF/NOTICE'
        exclude 'META-INF/RELEASE_NOTES.txt'
    }

如果还报错的话，就根据它给出的错误来添加，如下图，叫我们添加这个exclude 'META-INF/RELEASE_NOTES.txt'，我们就给它添加这个
