Eclipse:java.lang.OutOfMemoryError:PermGen空间

Question

我的eclipse配置.

Eclipse:最新版本(开普勒)

我的eclipse config.ini

-startup
plugins/org.eclipse.equinox.launcher_1.3.0.v20130327-1440.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.1.200.v20130521-0416
-product
org.eclipse.epp.package.standard.product
--launcher.defaultAction
openFile
-showsplash
org.eclipse.platform
--launcher.defaultAction
openFile
--launcher.appendVmargs
-vmargs
-Dosgi.requiredJavaVersion=1.6
-Xms40M
-Xmx512M

更新后从Juno到Kepler.But和configuration我没有遇到任何问题.

我面临的例外是

      [ERROR] Out of memory; to increase the amount of memory, use the -Xmx flag at startup (java -Xmx128M ...)

它一直在告诉我

[错误]内存不足; 要增加内存量,请在启动时使用-Xmx标志(java -Xmx128M ...)

这是我的VM args

可能是什么问题..

谢谢你的帮助.

来自Eclipse wiki -

为什么我得到一个java.lang.OutOfMemoryError:PermGen空间？

JRE设置的默认最大永久生成空间可能太小.这与最大允许的堆空间无关.您可以通过使用VM参数启动Eclipse来增加最大PermGen大小:-XX:MaxPermSize = 128m
