Ionic生成错误：:mergeDebugAssets无法合并源集文件夹

Question

每当我尝试运行"ionic build android“时，我都会得到这个错误，构建过程运行了一半，并在这一行之后显示错误：

:mergeDebugAssets
Could not merge source set folders: 

我已经在过去的24小时内尝试了所有可用的答案，但都不起作用，在将JDK更新到最新版本后，我开始收到这个错误。

到目前为止，我已经尝试过了。更新了Android SDK，移除了Android平台并将其添加回来，将android平台更新为android@6.2.2，从package.json文件中删除了所有开发依赖项尝试替换Android SDK中的tools文件夹，但没有任何工作。我的离子信息你的系统信息：

Cordova CLI: 6.5.0 
Ionic CLI Version: 2.1.18
Ionic App Lib Version: 2.1.9
ios-deploy version: 1.9.0 
ios-sim version: 5.0.10 
OS: macOS Sierra
Node Version: v6.11.0
Xcode version: Xcode 8.3.3 Build version 8E3004b

Answer 1

解决方案是删除semver目录。

为了解决这个问题，我从项目中删除了semver.min.js.gz和semver.browser.js.gz的所有实例。
