Android Studio启动配置

任何有助于说明如何设置Android Studio启动配置参数的帮助将不胜感激。我有在MAC上运行的Android Studio 2.2，以及在/Library/Java/JavaVirtualMachines/jdk1.8.0_77.jdk/Contents/Home上安装的SDK。我的问题是，当前的Android Studio实例通过引用嵌入式JDK来运行，而该JDK缺少我需要正确执行插件操作所必需的jar。

查看此IDE日志，我看到以下内容

我需要ether重置以下行，ext: /Applications/Android Studio.app/Contents/jre/jdk/Contents/Home/jre/lib/ext:以使其引用jdk1.8.0_77.jdk或向启动配置中添加额外的ext条目。

非常感谢
