如何使用EclipseGit“将版本与祖先进行比较”

我正在ubuntu 12.04上使用Eclipse4.3.2和EGIT3.3。 我用egit3.2尝试了eclipse4.3.2，用egit3.2尝试了eclipse4.3.1。Eclipse4.4M6和EGIT3.3，都给出了相同的错误

我设置了一个本地git存储库。当我显示历史记录，然后单击1提交并单击“将版本与祖先进行比较”时，我会收到这样一个错误：“打开编辑器失败”

你知道我如何解决这个问题吗

多谢各位

以下是我在.log中看到的内容：

如果文件不在Eclipse中导入的项目中，则似乎会发生这种情况。如果您正在查看的存储库仍然包含Eclipse项目，那么导入它们应该会有所帮助。否则，您可以将存储库内容作为常规项目导入Eclipse

有一种方法可以描述您遇到的相同问题。你可能想投票支持这个错误。将项目导入Eclipse更像是解决问题的一种变通方法，而不是解决方案
