IDEA reported that java could not find the symbol to solve the problem
tags: IDEA
Problem Description
Obviously the package exists but it reports java: Symbol not found
Resolution process
1. Baidu first, idea-file-invalidate caches/restart
The result is useless
2. Maven install
The result is useless
3. Delete target
The result is useless
4. Project Structure-"Modules" select the package file of your project, Marks as Sources
is useless.
1-4 is the successful experience of netizens, which failed in my case. I am also desperate.
5. Solved my brother
I built a java.lang.String class in the project to test the parent delegation mechanism before
Then just delete this class.
