How to Change Read-Only Status of Files in intellij

问题

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?

回答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.

回答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.

If you're using Mac. Follow bellow steps:

1. Open that file by Finder
2. Right click and select Get Info
3. In that File Info window, select Sharing and Permissions, change Privilege as you expected. Before changing, you would remember unlocking your change permission by click on a Locker Icon at bottom right.

For Mac, it definitely works:

sudo chmod -R 777 /YourDirectory

I was just having this issue and I finally figured out where I was going wrong.

Over an hour of suggestions from Google didn't help. It turns out I was on files selected in the -out > production > MyPath folder instead of the -src folder in my project sidebar. Selecting the -scr > MyClass file allows me to do what I want to do.

回答6:

On your top-left corner in the drop-down where you have Tests,Production,Problems switch/choose from Project or any other directory you've choosen to Packages, you'll have your packages editable, files in the Project folder are not editable although they end with .class extension.

回答7:

This error appears when the other user has created those files.
1. Right click on the file or folder to be deleted.
2. Choose reveal in folder option.
3. Delete the file and enter the password.
4. Files will be deleted.
