在Ubuntu 12.04中打开Eclipse Juno时出现“No more handles…”错误。

Question

从今天开始，每次我打开Eclipse时，都会弹出一个标题为“Problem Occured”的消息框，内容如下：

“无法获取更多句柄[未知的Mozilla路径（MOZILLA_FIVE_HOME未设置）]，可能的参数：{0}，{1}，{2}，{3} 无法获取更多句柄[未知的Mozilla路径（MOZILLA_FIVE_HOME未设置）]”

然后我点击“确定”并继续使用工作台，就会出现另一个错误提示：

“发生了SWT错误。建议您退出工作台。随后可能会出现其他错误，并且没有警告就会退出工作台。请查看.log文件以获取更多详细信息。”

“您要退出工作台吗？（是/否）”

然后我点击了“是”，并查看了.metadata文件夹中的.log文件，发现了这个很长的堆栈跟踪：

我进行了数小时的谷歌搜索，看到了各种不同的解决方案，但它们要么对我来说太复杂而无法理解（请参阅此处），要么根本不起作用。

我尝试了以下操作:

1. 编辑 /etc/environment 并添加 MOZILLA_FIVE_HOME=/usr/lib/firefox，但没有效果。
2. 编辑 eclipse.desktop 并将 Exec=/usr/bin/eclipse/eclipse 更改为 Exec=env MOZILLA_FIVE_HOME=/usr/lib/firefox /usr/bin/eclipse/eclipse，这时候 Eclipse 会在启动时卡住。
3. 从此处下载 XULRunner-1.9.2.19，并将MOZILLA_FIVE_HOME环境变量设置为我提取它的目录。我得到了一个新的错误消息:

...然后是极长的堆栈跟踪

请问有人能帮我解决这个问题吗？谢谢。

是的，Eclipse从来都不是特别稳定，而Juno版本更是如此，尤其是如果你安装了很多插件。就在今天，我不得不多次重启Eclipse才能解决一个错误，否则我的工作空间无法加载 - 最终我失去了所有的工作集设置和一个自定义视图... - thkala

没关系，我已经删除了工作区和Eclipse。 - ssgao

似乎将SWT浏览器从Mozilla切换到WebKit更容易。请参考https://dev59.com/_lbUa4cB1Zd3GeqPAqYx了解如何操作。 - vorburger

当您尝试启动时，是否打开了许多编辑器或视图？ - Chris Gerken

Answer 1

这对我刚刚起作用：

    sudo apt-get install libwebkitgtk-1.0-0

重新启动Eclipse。不需要其他下载或更改。

自从我更新到Neon.2后，我在Kubuntu 16.04上遇到了这个错误；每次打开“.md”文件（默认为wiki编辑器），都会出现这个错误。您的答案也解决了我的问题。 - Joe

如果您在64位Linux安装上使用32位Eclipse（带有32位JRE），则需要执行以下操作：sudo apt-get install libwebkitgtk-1.0-0:i386。没有:i386后缀，它将安装libwebkitgtk的64位库，而32位JRE无法加载。 - slowhand

Answer 2

如果您尝试从与启动X会话的用户不同的用户启动应用程序，则可能会收到此错误。
