Java Eclipse（和m2eclipse）的问题

我使用Eclipse时遇到了严重的问题：-（首先，我试图为您粗略地重建我的情况：

我安装了EclipseJavaEEHelios和JDK1.6.0_21，并配置了windows的系统变量

我安装了m2eclipse

我为一个JSFWebProject生成了一个原型

我使用Windows XP Professional SP3

所以…现在Eclipse出现了很大的问题。当我尝试打开pom.xml或使用一些特定于maven的选项时，Eclipse停止工作，并出现permgen空间错误，如我上一次会话中所示：

也许有问题？！有人有主意吗

编辑：我得说这样更好。这种问题很少发生

更新2： 请找人帮我配置我的eclips.ini，这样我就可以使用JDK 6-21了…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
-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，我按照船长的建议发布了另一个问题：

---

您需要通过在eclipse.ini中传递-XX:MaxPermSize=256m来增加最大perm大小

注意：对于Helios和您的java版本，请使用上述参数，使用其他参数（launcher.XXMaxPermSize）将无法工作，因为存在错误

请参阅以下链接中的更多内容：

---

我的EclipseGalileo也有类似的问题。在我更新JDK1.6.021之前，JDK6更新3一直运行良好

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

另一个对我有效的选项是添加运行->调试配置…->（您的Maven构建）->JRE选项卡->虚拟机参数一些虚拟机参数：

-Xms512m -Xmx1024m -XX:PermSize=256m -XX:MaxPermSize=512m -XX:NewSize=128m

希望这有助于

更新：

甚至，您可以将相同的参数添加到：

---

窗口->首选项->Java->安装的JRE->（您首选的JDK或Maven实例使用的JRE）->默认VM参数

请编辑该问题，而不是添加更新作为答案。根据您的更新，我认为这不是同一个问题。Permgen内存错误将导致异常，而不是导致eclipse陷入无休止的循环。我建议您查看eclipse日志，并可能发布另一个问题。是的。ini中设置的内存限制被VM忽略。

-Xms512m -Xmx1024m -XX:PermSize=256m -XX:MaxPermSize=512m -XX:NewSize=128m
