java - Eclipse 无法打开并显示 "an error has occurred"？

Question

我正在 Mac (Yosemite) 上运行 Eclipse Luna。

我已经使用 Eclipse 几个月了，今天早上当我打开 Eclipse 时，我在启动屏幕后收到一个弹出窗口，其中显示“发生错误，请参阅日志文件。”

我尝试过的:

• 使用 -clean 参数运行 Eclipse

• 我的资源元数据文件夹中没有要删除的 .snap 文件

• 完全删除我的工作区(好吧，重命名它)

不过它并没有超越启动屏幕。

这是日志文件，以防有帮助:

你用任务管理器杀死了jvm进程吗？如果这样做，您的工作区可能已损坏。您必须创建一个新的工作区。这种事在我身上发生过好几次。
