当我尝试访问Eclipse Mars上的网络设置时，为什么会出现“无效值”错误？

Question

我试图访问eclipse市场但它失败了，所以我去检查网络设置并得到了这个：

如果我继续“网络连接”选项卡最初没有加载但是在单击它之后加载它我可以加载但活动提供程序是空白的：

我尝试重启Eclipse，我得到同样的错误。

有没有人知道修复或解决此问题的方法？无论是破解Eclipse配置文件还是我不介意的事情 - 我只需要让Eclipse再次联机！

遵循建议here我用eclipse -clean运行了我的日食，并且属性窗口打开正常，我可以进入市场。我重新启动了eclipse，一切都还在运行，所以它似乎解决了这个问题。
