IntelliJ 找不到任何声明 [英] IntelliJ cannot find any declarations

问题描述

我完全卸载了 IntelliJ，现在重新安装并导入了我的项目.我使用 gradle 导入，可以看到我项目中的所有文件.但是，当我打开一个文件时，我无法通过执行 cmd + 单击找到任何要转到的声明.我有 Java 7 SDK 设置，我什至无法进入我自己项目中的类声明.转到像 String 或 List 这样的 Java 核心类也不起作用.如何让 IDE 能够找到我的类?

I completely uninstalled IntelliJ and have now reinstalled and imported my project. I imported using gradle and can see all of the files in my project present. However, when I open a file I can't find any declaration to go to by doing cmd + click. I have the Java 7 SDK setup, and I can't even go to the declaration of classes in my own project. Going to a Java core class like String or List doesn't work either. How can I enable the IDE to be able to find my classes?

我使用的是 OSX Yosemite，IntelliJ 2016.1.2 build 145.972.

推荐答案

我遇到了同样的问题，花了将近 15-16 个小时来清理、重建、使缓存失效、将 Idea 从 16.3 升级到 17.2，但都是徒劳的.我们有一个 Maven 管理的项目，并且构建曾经是成功的，但由于 Idea 看不到文件，因此无法在声明/实现之间导航.

I faced the same issue and spent almost 15-16 tiring hours to clean, rebuild, invalidate-cache, upgrade Idea from 16.3 to 17.2, all in vain. We have a Maven managed project and the build used to be successful but just couldn't navigate between declaration/implementations as Idea couldn't see the files.

在无休止地尝试解决此问题后，我终于意识到是 IDEA 设置导致了所有头痛.这就是我所做的(Windows系统):

After endlessly trying to fix this, it finally dawned to me that it's the IDEA settings causing all the headache. This is what I did (Windows system):

1. 退出 IDE
2. 递归删除项目目录中所有.iml文件 del/s/q "C:Dev runk*.iml"
3. 查找并删除所有.idea文件夹
4. 删除.IntelliJIdea2017.2system
下caches、index、LocalHistory文件夹的内容
5. 打开 Idea 并导入项目 ....

1. Exit IDE
2. Recursively delete all .iml files from project directory del /s /q "C:Dev runk*.iml"
3. Find and delete all .idea folders
4. Delete contents of the caches, index, and LocalHistory folders under <user_home>.IntelliJIdea2017.2system
5. Open Idea and import project ....
