错误：java.io.IOException：重复的zip条目

Question

我想用几天时间解决一个问题
当我运行应用程序时，出现以下错误：

Error:java.io.IOException: Duplicate zip entry 
[simple-xml-2.7.1.jar:org/simpleframework/xml/Attribute.class]

更详细地说（这里它说：simple-xml-2.7.1.jar，但我有一个类似于图中的simple-cxml-2.3.4.jar）

Error:java.lang.RuntimeException: java.io.IOException: Can't write [C:\Users\Alfonso\Documents\AndroidStudioProjectsNew\Business\VOIPMonitoring\app\build\intermediates\multi-dex\debug\componentClasses.jar]

Answer 1

几天后，我从一个新项目开始并逐步添加依赖项，解决了我的问题

这个问题是由我的gradle文件中的依赖项与外部库冲突引起的。

我发现了这一点感谢指挥

    ./gradlew app:dependencies > dependencies.txt 

其中 app 是您的项目模块。

冲突问题位于箭头所示的位置(--

您可以使用“排除模块”排除该依赖项，如下所示（但我更喜欢从新的空项目开始，之后我会排除依赖项问题）

例如，假设com.android.support:support-v4是包含导致这些错误的重复类的模块。下面是如何从依赖项中排除重复模块:

//Your dependency that includes the module with the duplicates.
 compile('com.my.project:my-module:0.1') {
    //exclude the offending module so there won’t be duplicates.
    exclude module: 'support-v4'
    //maybe you need to exclude a group also?...
    exclude group: 'com.google.android.gms'
}

Answer 2

simple-xml-2.7.1.jar，但我不使用它。。

您可能不会，但其他库中的一个会

简单的 XML JAR 不是 JNI 库，所以我不知道为什么你会把它放在 jniLibs 中，但是...

删除 JAR，请改用此依赖项

 compile 'org.simpleframework:simple-xml:2.7.1'

Answer 3

这可能是你的问题。您将< code > simple-XML-2 . 3 . 4 . jar 放在依赖项中，并且您的一些其他依赖项依赖于< code > simple-XML-2 . 7 . 1 . jar 。

使用 ./渐变

您最好尝试在不使用< code > simple-XML-2 . 3 . 4 . jar 的情况下进行编译，并查看代码是否可以使用< code > simple-XML-2 . 7 . 1 . jar 运行。
