MyEclipse 2017 CI 首选项错误 window
MyEclipse 2017 CI errors with Preferences window
已解决： 我通过创建一个新工作区解决了这个问题。我不确定到底发生了什么破坏了我的旧工作区，很难说也很难解决。
我刚刚安装了 MyEclipse 2017 CI 并转换了我的旧 2016 CI 工作区。我对我的主题做了一些改动，不太确定我做了什么，没有什么异常，重新启动了我的 Eclipse 客户端，现在当我尝试导航到 Window > Preferences.[=14 时出现错误=]
具体来说，当我第一次单击“首选项”时，出现此错误，并且“首选项”window 没有打开：
