我尝试增加内存，尝试使用最新的Eclipse靛蓝，但是会引发相同的错误.有人可以帮我解决该错误吗?

I tried to increase the memory , tried to use latest eclipse indigo but it throws the same error. Can somebody help me how should I resolve this error?

谢谢，马诺伊

推荐答案

您究竟如何增加内存?

尝试使用引用-Xms 和 -Xmx 玩吗?"rel ="nofollow">堆大小可用于Eclipse.有时还会增加 -XX:PermSize 和 -XX:MaxPermSize ( permgen )值也有帮助.

Try to play with -Xms and -Xmx that refer to the heap size available for Eclipse. Also sometimes increasing -XX:PermSize and -XX:MaxPermSize (permgen) values helps too.

例如，以下是我的 eclipse.ini 中的值(总RAM为8GB):

For example, here are the values from my eclipse.ini (having 8GB total RAM):

...

-vmargs
-XX:MaxPermSize=2048m
-Xms320m
-Xmx3072m

...
