Gradle 包装器给出错误“无法创建'AppPlugin'类型的插件”

Question

我创建了一个新项目并没有进行任何更改。当我尝试在该项目中使用 Gradle Wrapper 执行 Gradle 任务时，出现以下错误：

• 出了什么问题：评估项目 ':app' 时出现问题。无法创建“AppPlugin”类型的插件。

• 尝试：使用 --stacktrace 选项运行以获取堆栈跟踪。使用 --info 或 --debug 选项运行以获得更多日志输出。

构建失败

我使用的是装有 OS X 的 Mac：

项目设置：

• Gradle 版本：2.4
• 安卓插件版本：1.3.0
• JDK：1.7.0_71

堆栈跟踪：

Answer 1

我找到了导致这个问题的原因：
我使用gradlew cC 而不是./gradleW cC 运行命令，使用/Users/<username>/Library/Android/sdk/tools/templates/gradle/wrapper/gradlew 而不是项目的Gradle 包装器。呵呵
