Android Proguard issue with Gradle

Question

我是一名Android开发人员，我使用Gradle来构建我的项目，如果我使用Proguard，我会得到一个IOException，上面写着：

Execution failed for task ':ProjectName:proguardRelease'.
java.io.IOException: Can't write [:***buildinter mediatesclasses-proguardreleaseclasses.jar] (Can't read [:***buildintermediatesexploded-aarandroidMSFPush1.1.6libssupport -v4-19.1.0.jar(;;;;;;!META-INF/MANIFEST.MF)] (Duplicate zip entry [android/suppo rt/v4/app/p.class == support-v4-19.1.0.jar:android/support/v4/app/FragmentState. class]))

请帮忙，我该如何解决上述问题？

Answer 1

在build.gradle中，排除导致重复问题的实体：

packagingOptions {
    exclude 'META-INF/MANIFEST'
    exclude 'META-INF/LICENSE'
    exclude 'META-INF/NOTICE'
  }
