Eclipse属性面板错误

Question

每次启动属性面板时，我都会收到此错误:

Could not accept change: the currently displayed page contains invalid values.

我尝试使用全新的工作区和新安装的 eclipse，但没有任何结果。

我使用的是 Mac OS X。

欢迎任何帮助

这里有 2 个新的屏幕截图(全新加载的 Eclipse + 新工作区) alt text http://www.neverblind.eu/eclipse_error/4.jpg alt text http://www.neverblind.eu/eclipse_error/5.jpg

我在 eclipse 工作区 .log 文件中发现了错误:

Eclipse 有时会表现得很奇怪。你所有的源代码文件夹都好吗？请先检查所有文件夹。如果它们没问题，那么一定有核心插件或包含所有项目的工作区。

首先复制您的工作区，然后安装另一个 eclipse 实例。尝试在该 Eclipse 中打开工作区。

如果这不起作用，那似乎是个大问题。可能您需要在新工作区中再次导入所有项目。

为了获得更好的性能，您应该对工作区中的项目数量进行一定的限制。看来您在一个工作区中有很多项目，这可能会导致内存问题并减慢您的 Eclipse。

我希望这对您有用。

查了一下，好像是eclipse 3.4的一个bug。认为它显示了 WinXP 的一个错误，可能它也影响 MAC。

请检查下面的链接。他们指定了版本 3.4 M6。

因此，如果您使用旧版本的 Eclipse，请从此链接获取新版本。另请检查您的 Mac 上是否安装了 JDK 1.6(稳定版)。

Eclipse 下载:http://www.eclipse.org/downloads/

错误:https://bugs.eclipse.org/bugs/show_bug.cgi?id=217707

希望这有帮助。

谢谢。
