我使用Eclipse而且我遇到了严重的问题:-(首先我试着为你粗暴地重建我的情况：
我使用的是Windows XP Professional SP3
所以......现在Eclipse有很大的问题。当我尝试打开pom.xml或使用一些maven特定选项时，eclipse停止工作并发生permgen空间错误，就像在我上一次会话中一样：

我无法向自己解释，原因很多。也许有人有类似的问题，可以帮助我。
:-( 30分钟后，它再次泄漏： - （
似乎Eclipse仍处于无休止的循环中。 “Eclipse”任务不断使用我CPU的50％。
这很奇怪。这是我的eclipse.ini：
-startup
plugins/org.eclipse.equinox.launcher_1.1.0.v20100507.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.1.0.v20100503
-product
org.eclipse.epp.package.jee.product
--launcher.defaultAction
openFile
-XX:MaxPermSize=256m
-showsplash
org.eclipse.platform
--launcher.defaultAction
openFile
-vmargs
-Dosgi.requiredJavaVersion=1.5
-Xms128m
-Xmx512m
也许有问题？！？有人有想法吗？
编辑：我需要说它更好。这个问题很少发生。May Somebaody请帮我配置我的eclips.ini。所以我可以使用JDK 6-21 ......或者我应该使用旧版本？
到目前为止：
-startup
plugins/org.eclipse.equinox.launcher_1.1.0.v20100507.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.1.0.v20100503
-product
org.eclipse.epp.package.jee.product
--launcher.defaultAction
openFile
-XX:PermSize=128M
-XX:MaxPermSize=256m
-showsplash
org.eclipse.platform
--launcher.defaultAction
openFile
-vmargs
-Dosgi.requiredJavaVersion=1.5
-Xms128m
-Xmx512m
好的，我按照船长的推荐，发布了另一个问题： Trouble with Eclipse
答案 0 :(得分：10)
另一个对我有用的选择是添加运行 - >调试配置...-＆gt;（您的Maven版本） - ＆gt; JRE标签 - > VM参数一些VM参数：
-Xms512m -Xmx1024m -XX:PermSize=256m -XX:MaxPermSize=512m -XX:NewSize=128m
希望这有帮助...
已更新：
甚至，您可以将相同的参数添加到：
Window-＆gt;偏好设置 - ＆gt; Java-＆gt;已安装的JRE-＆gt;（您首选的JDK或Maven实例使用的JRE ） - ＆gt;默认VM参数< /强>
答案 1 :(得分：6)
你需要通过在eclipse.ini中传递-XX：MaxPermSize = 256m来增加你的最大烫发大小
注意：对于Helios和您的java版本，请使用上面的内容，使用其他参数（launcher.XXMaxPermSize）将因为一个错误而无效。
在以下链接中查看更多信息： http://wiki.eclipse.org/FAQ_How_do_I_increase_the_permgen_size_available_to_Eclipse%3F
答案 2 :(得分：0)
我的日食伽利略似乎有类似的问题。使用JDK 6 update 3时，它一直工作正常，直到我更新了我的jdk 1.6.0_21。
当我将JDK路径更改为指向Jdk 6 update 3时，它开始正常工作。
希望这有帮助!!!
谢谢， Amit Chhajed
