任务“：app：TransformClassesWithDesugarForDebug”执行失败

Question

我刚刚更新了我的cordova android到7.1.0，以支持Android27 sdk，以解决插件不能与SDK26一起工作的问题。

我尝试更改GradleBuilder.js文件中的gradle分发url，但没有成功。

编辑2：我想解决这个问题的firebase插件似乎是问题的一部分。移除：cordova-plugin-firebase允许应用程序的构建没有问题。似乎在添加插件后，我不能简单地用：ionic cordova plugin remove cordova-plugin-firebase删除它

它给出了以下错误：

missing file :: app/src/main
Error during processing of action! Attempting to revert...

(node:11396) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 1): Error: Uh oh!
ENOENT: no such file or directory, open 'C:\Users\Boogaloo\WebstormProjects\IONIC\programs\myApp\platforms\android\AndroidManifest.xml'

编辑3：该问题可能是Firebase插件和对讲机插件之间的冲突https://github.com/arnesson/cordova-plugin-firebase https://github.com/Intercom/intercom-cordova

Answer 1

问题是不同的插件对同一个库有不同的依赖关系。为了解决这个问题，我必须在build.gradle文件中启用multidex。进行更改的build.gradle文件位于Platforms>Android>App中

android{

  defaultConfig{

    multiDexEnabled true
  }
}
