这是由 google GWT 插件引起的。我使用 STS 欢迎页面按钮安装了该插件:

所以我必须拥有最新版本。我尝试请求更新，但没有报告该插件的更新。此时我无法离开 GWT，那么我该如何解决这个问题呢？

Answer 1

当前版本的 GPE 对于 mars 来说已损坏，这意味着会发生此异常。在不久的将来，这个问题将会得到解决。

在那之前，我在 fork 中有一个解决方法，可以在 mars 中解决这个问题。在这里下载 GPE 插件的分支: http://gwt-plugins.github.io/documentation/gwt-eclipse-plugin/Download.html

按照下载页面上的说明进行操作。
