每次我试图建立一个APK，这个错误不断显示！？我已经尝试了几乎所有的soultoins提到的网站上，但没有运气！
错误：执行任务“：app：transformClassesWithJarMergingForDebug”失败。
com.android.build.api.transform.TransformException:java.util.zip.ZipException:重复条目：com/google/gson/annotations/Expose.class

以下是我尝试过但不起作用的一些解决方案：
1.我已经添加了transitive = true; exclude group: 'com.google.code.gson', module: 'gson' for改型and条带依赖项
1.我删除了gson依赖项
1.我想删除gson库的jar文件，但在libs文件夹中找不到它！？

1. multiDexEnabled true已添加，但没有任何效果
   1.我删除了compile fileTree(dir: 'libs', include: ['*.jar'])
   我想它与**Zoom模块或Stripe**有什么帮助吗？！
