Eclipse（和 m2eclipse）的问题

Question

我使用 Eclipse 并且遇到了严重的问题:-( 首先，我尝试粗鲁地为您重建我的情况：

1. 我安装了 Eclipse Java EE Helios 和 JDK 1.6.0_21 并配置了 Windows 系统变量
2. 我安装了 m2eclipse
3. 我为 JSF Web 项目生成了一个原型

我使用 Windows XP Professional SP3

所以...现在 Eclipse 有很大的问题当我尝试打开 pom.xml 或使用某些 Maven 特定选项时，Eclipse 停止工作并发生永久空间错误，就像我上次会话中的那样

：我无法向自己解释这一点，也许有人遇到了类似的问题，可以帮助我解决这个问题

：

:-( 30 分钟后，它再次开始泄漏:-(

似乎 Eclipse 仍然处于无休止的状态。任务“Eclipse”连续使用我的 CPU 的 50%，

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？！？

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
-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

好吧，我按照船长的建议并发布了另一个问题： Eclipse 出现问题

Answer 1

对我有用的另一个选择是添加运行->调试配置...->(您的 Maven 构建)->JRE 选项卡->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...

更新：

或者甚至，您可以将相同的参数添加到：

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

Answer 2

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，请使用上述内容，使用其他参数 (launcher.XXMaxPermSize) 将不起作用，因为漏洞。

请参阅以下链接了解更多信息：
http://wiki.eclipse.org/FAQ_How_do_I_increase_the_permgen_size_available_to_Eclipse%3F

https://bugs.eclipse.org/bugs/show_bug.cgi?id=319514

Answer 3

我的日食伽利略也有类似的问题。在 JDK 6 update 3 中它一直运行良好，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，
