知道怎么解决吗？

Answer 1

XUL Runner运行时环境版本高于1.9.0.x时会出现此问题，例如版本1.9.1。

您可以通过运行以下命令来确定已配置的XUL Runner运行时环境版本：

xulrunner -v

编辑eclipse.ini文件。找到-vmargs行并添加一个新行以使用以下语法指定XUL Runner运行时环境的版本：

-Dorg.eclipse.swt.browser.XULRunnerPath=/usr/lib/xulrunner-1.9.x.x

Answer 2

对我来说，增加--launcher.XXMaxPermSize 256m中的512m eclipse.ini工作了{{1}}。一旦Eclipse加载了许多插件和功能，Eclipse就会在启动时加载这些新的插件/功能时需要额外的空间。

Answer 3

报告此类邮件的所有错误（例如bug 260772或bug 239681）都提到 XulRunner ：您最近没有安装它？

Eclipse / SWT 3.4支持任何   mozilla / seamonkey / xulrunner / firefox-iff-dynamic-linked＆gt; = mozilla 1.4。

从FireFox3开始，FireFox附带了一个私有的xulrunner供其使用，但这不是一个完整的安装，浏览器可以指向独立于它附带的FireFox。   但是如果FireFox是动态链接的，那么浏览器可以使用它（FireFox），而FireFox正在使用私有xulrunner来完成它的工作只是一个   浏览器不知道/不关心的实现细节。

如果您安装了xulrunner 1.9~b5 + nobinonly-0ubuntu3，那么Eclipse 3.4不起作用 - 您安装或卸载的FireFox版本似乎并不重要

另一个原因与某些工作空间损坏有关，这可能解释了为什么OP balderman注释：

我找到了一种方法来启动eclipse，方法是在文件RECENT_WORKSPACES=bla bla中注释掉org.eclipse.ui.ide.prefs行：作为问题“How to delete obsolete workspace in RAD?”，实际上并没有删除工作区，但允许跳过可能存在某种腐败问题的那个。

Answer 4

你得到：

org.eclipse.swt.SWTError: No more handles

每次你开始？这意味着Eclipse的操作系统资源不足，您是否打开了许多其他应用程序？尝试关闭已运行的其他一些应用程序。

如果您没有运行许多其他应用程序，您可能需要考虑使用sleak，eclipse插件可以监视eclipse和eclipse RCP的使用情况。

您是在运行纯Eclipse，还是安装了许多插件？如果vanilla Eclipse没有手柄，我会感到很惊讶......它更可能是由插件引起的（根据我的经验）。

Answer 5

backup“.. \。metadata.plugins \ org.eclipse.core.resources”forler
empty“.. \。metadata.plugins \ org.eclipse.core.resources \ .safetable \ org.eclipse.core.resources”file
运行Flex。您的项目列表将为空
关闭Flex
恢复“.. \。metadata.plugins \ org.eclipse.core.resources”文件夹（覆盖全部）
运行Flex。
