Eclipse 3.7 靛蓝 : "About dialog" error

Question

我最近将 Eclipse 3.6 实例升级到 3.7。

我想查看“帮助”->“关于 Eclipse”选项，但未显示此对话框。

使用 -consoleLog -debug 选项运行它以了解可能出现的问题。这就是我所看到的，有什么想法吗？

顺便说一句，我也在 E​​clipse 平台讨论论坛上发布了这个问题:http://www.eclipse.org/forums/index.php/m/692851/#msg_692851

Answer 1

这可能取决于您升级时拥有的插件。

例如，Eclipse bug 347642由于来自 Scala 插件的错误，已被关闭为“Not Eclipse”。
(参见此thread on Scala user.group)

因此，它不太可能与 Eclipse Indigo 单独相关，而是与插件的某些副作用有关。
顺便说一句，我总是更喜欢在当前的 Eclipse 旁边安装一个新的 Eclipse，并引用相同的工作区，以便单独测试新版本:如果存在太多问题，我总是可以安全地返回到以前的(未触及的) ) Eclipse 版本。
