Android studio 无法完成 Gradle 执行

Question

我已将我的 android studio 版本更新为 2.2，但在项目启动时收到错误消息：

Gradle project refresh failed.

所以我搜索了这个问题并安装了 Java SE Development Kit 8u101 并将 JDK 位置设置为它。 执行此错误后出现：

    Information:Gradle tasks [:app:generateDebugSources, :app:mockableAndroidJar, :app:prepareDebugUnitTestDependencies, :app:generateDebugAndroidTestSources]
Error:Failed to complete Gradle execution. Cause: unknown.

我被这个 gradle 执行错误困住了。我已经卸载了我更新并安装了新的 android studio。 我在新安装的android studio 2.2版本中也面临上述问题。 目前JDK位置

C:\Program Files\Java\jdk1.8.0_101

在 gradle.properties 里面

org.gradle.jvmargs=-Xmx256m

我的系统配置是：

处理器 -> intel core i3，RAM -> 4 gb，操作系统类型 -> 32 位 Windows 7 Ultimate OS

带有 --stacktrace --debug 的 Gradle 控制台：

1. 卸载 Android Studio
2. 删除 Android SDK
3. 卸载所有版本的JDK
4. 删除用户文件夹的 .android、.AndroidStudio2.2 和 .gradle 文件夹
5. 重新启动计算机
6. 下载并重新安装 Android Studio
