项目属性中的Eclipse错误

时间：2016-04-15 00:12:53

标签： eclipse eclipse-cdt

我在我的Antergos（基于Archlinux）操作系统上安装了Eclipse，我想更改项目的C / C ++版本中的设置，但是当我尝试打开它时，我收到以下错误：

Eclipse Project Properties Error

此错误之后是Java异常（NullPointerException）。

我尝试更新Eclipse，但它已经是最新的。我也尝试重新启动应用程序并清理/构建但无济于事。 直到今天，我从未遇到过这样的问题。我想也许这是一个新的更新，但我找不到其他遇到同样问题的人。

此错误意味着什么以及如何解决？

编辑：以下是.log文件的内容：

此问题已在此处报告：

https://git.eclipse.org/c/platform/eclipse.platform.swt.git/commit/?id=1a375bfbb7dca92b102db09891a18eeb80d671f2

https://bugs.eclipse.org/bugs/show_bug.cgi?id=486069

我认为Archlinux用户似乎是第一个看到它的人，因为Arch软件包始终是最新版本，并且最近更新了Gtk和Wayland库。
