我使用 Eclipse，但我遇到了严重的问题 :-( 首先，我尝试粗鲁地为您重建我的情况：
- 我安装了 Eclipse Java EE Helios 和 JDK 1.6.0_21 并配置了 windows 的系统变量
- 我安装了 m2eclipse
- 我为 JSF Webproject 生成了一个原型
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，就像我上次会话中的这里一样：

我无法对自己解释，有很多原因。也许有人有类似的问题，可以帮助我。
更新：
:-( 30 分钟后又开始漏水 :-(
Eclipse 似乎仍然处于无限循环中。'Eclipse' 任务持续使用我大约 50% 的 CPU。
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。
更新 2：
请 Somebaody 帮助我配置我的 eclips.ini。这样我就可以使用 JDK 6-21 ... 或者我应该使用旧版本吗？
到目前为止就是这样：
-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
