我有一个 Android Studio 项目，我想开始使用 Intellij 14 Ultimate 来利用它提供的一些很酷的功能。当我尝试打开我的项目时，我收到一条消息：
Gradle 同步
Android Gradle 插件版本 1.0.0-rc4 需要 Gradle null 或更高版本。未找到本地 Gradle 发行版....
单击“确定”以使用 Gradle 包装器。
我单击确定并尝试同步，但失败。这是错误控制台的内容：
需要 Gradle 版本 2.2。当前版本是 2.1。如果使用 gradle 包装器，请尝试编辑 ~gradle-wrapper.properties 中的 distributionUrl~
我修改文件点击“再试一次”
什么都没发生。以下是日志文件中的内容：

我也尝试过导入项目并得到类似的结果。有任何想法吗？
