我有一个刚刚超过方法限制的Android应用程序，所以我尝试启用multidex。一旦我这样做，我得到以下错误：

项目正在Kotlin开发，使用Android Studio 3.0，gradle plugin 3.0.0。
我试过没有明确地将依赖关系放在依赖关系部分，我尝试从“设计”中排除（据我所知，这是唯一依赖传递带来multidex的依赖），我尝试使用multidex 1.0.1,1.0.2但似乎没什么用。
我已经没想完了。如果我切换到“开发”味道，神秘地起作用。
答案 0 :(得分：0)
您可能不需要自行导入Multidex。 Multidex包含在android.support中，它可能与您尝试自行导入的multidex冲突。尝试删除该行，看看它是否有效。
此外，＆＃34;构建口味的原因＆＃34;工作是因为您的发布版本指向要遵循的proguard文件。如果你的proguard文件有-keep class android.support.*，我很好奇，这就是multidex失败的原因。
希望这有帮助！
答案 1 :(得分：0)
对于这个完全相同的问题，我们有一个绝对值得称赞的原因：
debugImplementation "com.android.support:multidex:1.0.2"
我们项目中的release有一个android.support.multidex.MultiDex构建风味特定实现，包含所有包，所有内容都是空的（无效）。
因此删除违规类会修复构建。
implementation "com.android.support:multidex:1.0.2"
答案 2 :(得分：0)
最近，我遇到了这个问题，下面是我收到的异常消息
(Duplicate zip entry [multidex.jar:android/support/multidex/MultiDex$V14.class]))
我不知道此问题的背景，但此问题的根本原因是
当删除并尝试构建APK时，它起作用了！
！不错的解决方案！
