推荐答案

听起来您需要以更大的内存限制启动 JVM.尝试类似的操作(如果您使用的是 Bourne shell):

It sounds like you need to launch your JVM with a larger memory limit. Try something like (if you're using Bourne shell):

export ANT_OPTS=-Xmx1g
ant

或者，如果您在 Windows 下使用 cmd:

or, if you use cmd under Windows:

set ANT_OPTS=-Xmx1g
ant

上面，1g 表示 1 GB.您可以将其调整为您喜欢的任何内容；例如，如果要使用 1.5 GB，则可以使用 -Xmx1536m.

Above, the 1g means 1 GB. You can tweak that to whatever you like; for example, if you want to use 1.5 GB, you can use -Xmx1536m.
