Gradle 项目同步失败，没有消息，在命令行上工作
Gradle project sync failed without Messages, worked on command-line
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 有效。 "Messages" 视图中没有消息。在idea.log中，出现了以下NullPointerException：

Using Invalidate Caches/Restart and removing the .gradle folder 没有帮助。为什么是这样？它是如何固定的？
在设置 > 构建、执行、部署 > Gradle 中取消设置本地 gradle 分发后（为调试此问题而设置），Android Studio 提出更新到 gradle:3.0.1 来自 gradle:3.0.0。这修复了它。
之前采取的步骤：
- 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
将 Android Studio 升级到 3.1.3 后，我遇到了类似的错误。我不记得我之前使用的确切版本 -- 第 2 版系列。
我收到这些错误的原因是因为我使用的 Gradle 插件版本太低。
buildscript {
dependencies {
classpath 'com.android.tools.build:gradle:2.2.3'
...
}
一旦我将版本从 2.2.3 更新到 2.3.3，Android Studio 就能够继续并给我更有意义的错误消息，例如
Gradle sync failed: Minimum supported Gradle version is 3.3. Current version is 2.14.1. If using the gradle wrapper, try editing the distributionUrl in gradle/wrapper/gradle-wrapper.properties to gradle-3.3-all.zip
从那里开始，只需解决版本兼容性问题即可。
对我来说，这是一个简单的解决方案：我从我的项目中删除了一个模块，但忘记从 settings.gradle
中删除它
也许这可以帮助某人
