How to Change Read-Only Status of Files in intellij

Question

I have a Java project and I want to modify it in intellij but I can't do it because of this " read-only file " or "file is not writable" , so how I can modify and execute it?

Answer 1

To toggle read-only attribute of a file, open file in the editor, or select it in the Project tool window. Do one of the following:

• On the main menu, choose File | File Properties | Make File Read-Only, or Make File Writable.

• Click the lock icon in the Status bar in the bottom right corner.

Answer 2

If IntelliJ IDEA is unable to change the file permissions using File | Make File Writable, then perhaps another user is owning that file, e.g. root (use this command to verify: ls -hal /path/to/File.java)

If someone else owns it, for whatever reason, you can change the permissions yourself using the chown command in the terminal:

sudo chown yourusername /path/to/File.java,

where yourusername is the same user that you used to launch Intellij IDEA.
