android – Gradle项目同步失败,没有消息,在命令行上工作
作者：互联网
在Android Studio中,同步失败：
Gradle project sync failed. Basic functionality (e.g. editing, debugging) will not work properly.
命令行gradle installDebug工作. “消息”视图中没有消息.在idea.log中,出现以下NullPointerException：

Using Invalidate Caches/Restart and removing the .gradle folder没有帮助.为什么是这样？它是如何修复的？
解决方法:
在设置>中取消设置本地gradle分发后构建,执行,部署> Gradle(设置用于调试此问题),Android Studio提供更新为gradle：3.0.1 from gradle：3.0.0.这解决了它.
以前的步骤：
>将google()存储库添加到buildscript和allprojects
>将compileSdkVersion和targetSdkVersion升级到27
>将所有com.android.support库升级到26.1.0
