从Eclipse运行ant时的javac:java.lang.OutOfMemoryError

Question

我已经在ini文件中给了eclipse大量的内存,但它仍然没有使用任何超过300mb的东西,我可以在任务管理器中看到.

  [javac] The system is out of resources.

这是我的ini文件.

--launcher.defaultAction
openFile
--launcher.XXMaxPermSize
512M
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize1024m
--vm
C:\Program Files\Java\jdk1.6.0_24\bin\javaw.exe -vmargs -Xms512m -Xmx1024m

我不知道为什么它不会使用我给它的内存.我还需要做任何其他事情来改变堆大小吗？

谢谢

不是Eclipse耗尽内存,而是蚂蚁.Ant作为eclipse的外部工具运行,因此它不会继承您用于eclipse的VM设置.您可以在外部工具运行配置中为其设置选项.转到运行 - >外部工具 - >外部工具配置...然后在"Ant构建"下,您必须查找您的ant构建,并且可以在JRE选项卡中设置vm参数.
