java - 插件更新后 Eclipse Juno 无法打开我的工作区

Question

刚刚我更新了 eclipse juno 中的插件。

更具体地说 GWT 2.5 development plugin .

我安装成功后，它要求重启。之后它退出，当试图重启时出现错误

"Unable to open the workbench,see the error logs"

很抱歉从日志中转储了所有异常，我在这里没有找到任何线索。

Eclipse 工作区的问题往往很痛苦。尝试转到您的安装路径，找到 configuration\org.eclipse.equinox.simpleconfigurator\。

打开bundles.info，然后删除org.eclipse.core.commands的低版本重复条目。然后使用 -clean 选项重新启动 eclipse。
