为什么这么红？ IntelliJ似乎认为无法找到/解决每个声明/方法 [英] Why so red? IntelliJ seems to think every declaration/method cannot be found/resolved

问题描述

我刚刚重新安装了已安装的IntelliJ，每个Java文件都会出现RED。我检查了JSDK，它是1.6。##。 Maven clean install build工作得很好。

I just re-installed installed IntelliJ, every Java file is coming up RED. I checked the JSDK, it is at 1.6.##. The Maven clean install build worked just fine.

如何解决这些错误错误？只需单击按钮就可以进行导航，这非常烦人。

How do I fix these false errors? It's very annoying not being navigate around with a click of buttons.

推荐答案

IntelliJ有时会自行混淆，即使没有外部Korgen所描述的变化（尽管这是一种很好的方式来重现它）。

IntelliJ sometimes gets confused all by itself, even without the external changes Korgen described (though that is a good way to consistently reproduce it).

单击文件 - >同步，IntelliJ应该会看到一切正常。

Click File -> Synchronize, and IntelliJ should see that everything is okay again.

如果这不起作用，IntelliJ的缓存可能会损坏（过去常常比现在发生的情况多得多）;在这种情况下，重新生成它们

If that doesn't work, IntelliJ's caches might be corrupt (this used to happen a lot more often than it does now); in that case, regenerate them by

单击文件 - >使缓存无效并重新启动IDE

（尽管在重新创建缓存时加载项目需要一段时间）。

(though loading the project will take a while while the caches are recreated).
