我在项目中使用了多个Android库和模块。每个都有自己的v4.Support库。我正在获取
java.util.zip.ZipException：重复条目 。当我在项目中搜索重复的类文件时，由于每个库中都有多个v4.support
lib，这些类有多个文件。我知道这个问题在这里已经被问过很多遍了，但对我来说却无济于事。

我的问题是：如何删除这些多个v4.support文件？我只想将此v4.support lib放一次，所有其他模块都应从那里引用它。我该如何实现？

以下是我的build.gradle脚本

// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
    repositories {
        mavenCentral()
        maven { url 'https://maven.fabric.io/public' }
    }

我收到这样的错误。每次我清理项目时，项目都会成功完成。但是，当我尝试给出Run命令时，它显示以下类型的错误。
