Question

我正在开发android app。最近，我从项目中删除了activation.jar和mail.jar，然后将其添加回来。将它们添加回来后，尝试运行我的application我收到以下错误：

Error:Execution failed for task 
':app:transformResourcesWithMergeJavaResForDebug'     
com.android.build.api.transform.TransformException: 
com.android.builder.packaging.DuplicateFileException: Duplicate files copied in APK META-INF/mimetypes.default

File1: C:\Android\Workspace\WeekendMovieRating\app\libs\activation.jar
File2: C:\Android\Workspace\WeekendMovieRating\app\libs\mail.jar

我用Google搜索解决方案并尝试了以下解决方案;

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'
}

我在gradle.properties中添加了上述代码，并尝试运行application但仍然收到相同的error。

然后我在观察我的error消息之后添加了以下代码：

exclude 'META-INF/mimetypes.default'
exclude 'META-INF/mailcap.default'

添加上述行后，它显示为BUILD SUCCESSFULL，但显示为240 errors。

Error:warning: Ignoring InnerClasses attribute for an anonymous inner class

Answer 1

您获得的错误与Proguard相关，与您最初发布的重复文件问题无关。

您应该相应地更新您的标题和说明以反映出来。

除非您提供有关proguard问题的更详细信息，否则很难解决。

您可以查看此similar问题，了解需要添加到proguard配置中的内容。

packagingOptions {
    pickFirst 'META-INF/mailcap.default'

    pickFirst 'META-INF/LICENSE.txt'
    exclude 'META-INF/DEPENDENCIES'
    exclude 'META-INF/LICENSE'
    exclude 'META-INF/LICENSE.txt'
    exclude 'META-INF/license.txt'
    exclude 'META-INF/NOTICE'
    exclude 'META-INF/NOTICE.txt'
    exclude 'META-INF/notice.txt'
    exclude 'META-INF/ASL2.0'
    exclude 'META-INF/mimetypes.default'
    exclude 'META-INF/mailcap.default'
}

将此用于包装选项

APK META-INF / mimetypes.default
