Question

我正在开发一个maven项目，一切都按预期工作，直到今天我决定将spring版本从3升级到4.点击Maven-＆gt;更新项目并出现此消息：

目前无法使用所选操作

不确定这是否相关，但这是我的pom.xml：

有什么想法吗？

Answer 1

我知道问题已经过时了，但是因为我仍然遇到同样的错误：尝试删除

C：\ Users \用户提供yourname \工作空间\ .metadata位于\ .plugins \ org.eclipse.e4.workbench \ workbench.xmi

对我而言，每次都有效。如果问题仍然存在，请避免以不错的方式关闭Eclipse，而只是杀死进程。

我知道，我知道......不是最好的解决方案，但仍然是一个快速的解决方案。 Neon没有引入此错误，但也出现在旧版本中。所以我猜它与Maven而不是Eclipse有关。

Eclipse Neon + Maven =所选操作不可用
