android - QtCreator 甚至无法构建空项目 - 执行此行时发生以下错误

修复方法如下:

Go to Start->Control Panel->System->Advanced(tab)->Environment Variables->System Variables->New:
Variable name: _JAVA_OPTIONS
Variable value: -Xmx512M



Variable name: Path
Variable value: ;C:\Program Files\Java\jre6\bin;F:\JDK\bin;
Change this to your appropriate path.
