How to configure IDEA so that when changing the class name in the java file, the mainClassName in build.gradle automatically changes?
1. File structure:
Boxy directory:
src
main
java
code file

build.gradle

2. Modules imported from build.gradle config file
3. Java code:
public class newLO {
public static void main(String[] args){
System. out.println("Hi!");
}
}

4. It is necessary that when changing the class name in the java file, IDEA notices the change and suggests changing (DO refactor) the class name in the build.gradle configuration file:
apply plugin: 'java'
apply plugin: 'application'
mainClassName = "newF"

Only the file name changes at the moment, the value of mainClassName = "newF" remains the same.
