在 Android Studio 中，同步失败：

Gradle 项目同步失败。基本功能（例如编辑、调试）将无法正常工作。

命令行gradle installDebug工作。“消息”视图中没有消息。中idea.log，出现了以下内容NullPointerException：

使用Invalidate Caches/Restart和删除.gradle文件夹没有帮助。为什么是这样？它是如何固定的？

在 Settings > Build, Execution, Deployment > Gradle（为调试此问题而设置）中取消设置本地 gradle 分发后，Android Studio 提供更新到gradle:3.0.1from gradle:3.0.0. 这解决了它。

之前采取的步骤：

  • 将google()存储库添加到buildscript和allprojects
  • compileSdkVersion将, 和 升级 targetSdkVersion到 27
  • 将所有com.android.support库升级到26.1.0

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，却忘了从settings.gradle

也许这可以帮助某人

将我的 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——版本 2 系列。

我收到这些错误的原因是我使用的 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 更新2.2.3为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 同步失败：支持的最低 Gradle 版本为 3.3。当前版本是 2.14.1。如果使用 gradle 包装器，请尝试将 gradle/wrapper/gradle-wrapper.properties 中的 distributionUrl 编辑为 gradle-3.3-all.zip

从那里开始，这只是解决版本兼容性问题的问题。
