Android Proguard 警告：无法写入资源（重复的 zip 条目）

我启用了 proguard 并得到：

Warning:can't write resource [META-INF/LICENSE.txt] (Duplicate zip entry [commons-io-2.4.jar:META-INF/LICENSE.txt])
Warning:can't write resource [META-INF/NOTICE.txt] (Duplicate zip entry [commons-io-2.4.jar:META-INF/NOTICE.txt])
Warning:can't write resource [META-INF/LICENSE.txt] (Duplicate zip entry [commons-collections-3.2.1.jar:META-INF/LICENSE.txt])
Warning:can't write resource [META-INF/NOTICE.txt] (Duplicate zip entry [commons-collections-3.2.1.jar:META-INF/NOTICE.txt])
Warning:can't write resource [META-INF/LICENSE.txt] (Duplicate zip entry [joda-time-2.7-no-tzdb.jar:META-INF/LICENSE.txt])
Warning:can't write resource [META-INF/NOTICE.txt] (Duplicate zip entry [joda-time-2.7-no-tzdb.jar:META-INF/NOTICE.txt])

Warning:can't write resource [.readme] (Duplicate zip entry [classes.jar:.readme])
Warning:can't write resource [META-INF/LICENSE.txt] (Duplicate zip entry [commons-lang-2.6.jar:META-INF/LICENSE.txt])
Warning:can't write resource [META-INF/NOTICE.txt] (Duplicate zip entry [commons-lang-2.6.jar:META-INF/NOTICE.txt])

这是什么意思？ 我应该排除像这里这样的东西吗？

configurations {
    all*.exclude group: 'commons-logging', module: 'commons-logging'
}

您正在使用带有重复文件的库，这是 gradle 中的一个错误，为了解决这个问题，请在您的项目 build.gradle 中使用它

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