Find convenient way to handle the .idea folder

[ammerzon]

Right now, the name of the JVM is hardcoded in the Gradle file, which is a problem if your JVM in IntelliJ has a different name. Additionally, changes to the JVM / project structure are picked up as version control changes, which we want to avoid.

Definition of Done

• [ ] The project can be imported into any JetBrains IDE regardless of the installed JVM name
• [ ] The Jetbrains IDE support is OS independent
• [ ] Changes to the project structure are not tracked in the version control

Tasks

• [ ] Find a feasible solution
• [ ] Sync with the project maintainers about the proposed solution
• [ ] Implement the accepted solution
• [ ] Document solution (DEV-GUIDE.md)
• [ ] Test solution on different operating systems

Additional context

• Possible idea would be a script that creates the .idea contents
• Think about how to do it - should we use Gradle, Bash / CMD?
