如何修复损坏的 Intellij Idea？

Question

When I open an existing Maven project, the IDE shows only those files on the root directory, but not any directories in the project. After a while, the IDE will show the project as what it is in the file structure, but not the directory types such as source code, test when I reopen the project. I reinstall the community edition, but the problem still resists. I have experienced the same issue for a few Java projects lately.

How to resolve this issue?

Answer 1

1, Please ask another teammate to check if that project really works. Sometimes the application structure already broken, then it is not your local problem.

2, There is a.idea folder in the application, delete it. Or simply, you git clone a new place Important: Please notice if you have edited / created some new files in the original directory, otherwise you would lost them if you delete the application.

3, Open intellij, and File -> Invalite caches

Personally, the second point is recommendated.

Answer 2

Try to click on Reload All Maven Projects in Maven tool window:

If it doesn't help you can try to perform the following actions:

• Close the project with File | Close ProjectFile | Close Project .
• Close the IDE.
• Open your project in OS file manager and remove all.iml files and the.idea directory.
• Reimport the project.

If the problem remains contact JetBrains support and attach a compressed log folder along with the project structure tree.
