我正在尝试配置 proguard 并遇到了一些按优先级排序的问题：
我收到了有关重复 zip 的警告并且无法修复它。我在“libs”目录中使用外部库和 2 个库项目（一个库项目有一个外部库 - 仅添加到项目中一次），它们仅添加到项目中一次。我试图将我的外部 jar 移动到另一个目录，即“lib”——只是重命名，因为一些用户已经设法解决它，但它对我没有帮助。另一种方法是尝试在基本 build.xml 中实现 custom_rules，因为它可以帮助一些用户避免这些警告。但是它的一切都对我没有帮助，我该如何解决？日志：
ProGuard: Warning: can't write resource [META-INF/MANIFEST.MF] (Duplicate zip entry [jackson-annotations-2.1.4.jar:META-INF/MANIFEST.MF]) ProGuard: Warning: can't write resource [META-INF/MANIFEST.MF] (Duplicate zip entry [android-support-v4.jar:META-INF/MANIFEST.MF]) ProGuard: Warning: can't write resource [META-INF/MANIFEST.MF] (Duplicate zip entry [google-analytics-v2.jar:META-INF/MANIFEST.MF]) ProGuard: Warning: can't write resource [META-INF/MANIFEST.MF] (Duplicate zip entry [jackson-core-2.1.4.jar:META-INF/MANIFEST.MF]) ProGuard: Warning: can't write resource [META-INF/MANIFEST.MF] (Duplicate zip entry [httpclientandroidlib-1.1.2.jar:META-INF/MANIFEST.MF]) ProGuard: Warning: can't write resource [META-INF/MANIFEST.MF] (Duplicate zip entry [deviceprint-lib-1.0.0.jar:META-INF/MANIFEST.MF])最后一件事是签名 apk 构建过程中的一些注意事项：
