我有一个junit蚂蚁构建的问题,我收到一个java.lang.OutOfMemoryError: PermGen space错误.

我正在尝试设置ANT_OPTS为ANT_OPTS='-Xmx512m -XX:MaxPermSize=256m'在构建Java Options中增加堆大小的ant构建工具.

但每次运行时我都会收到错误:

Exception in thread "main" java.lang.NoClassDefFoundError: ANT_OPTS=-Xmx512m -XX:MaxPermSize=256m
Caused by: java.lang.ClassNotFoundException: ANT_OPTS=-Xmx512m -XX:MaxPermSize=256m

    at java.lang.ClassLoader.loadClass(ClassLoader.java:248)
Could not find the main class: ANT_OPTS=-Xmx512m -XX:MaxPermSize=256m.  Program will exit.

语法错误？

谢谢.
