Bug description:

The auto format icon no longer appears in Java replits.

Expected vs Current Behavior:

I expect the auto format icon to appear in the editor for a Java replit, but it does not.

Steps to reproduce:

Create a Java replit. Look for the auto format icon.

Bug appears at this link:

My students all report the same problem on their various operating systems and browsers.

Thank you! It happens with every Java replit. Here’s one: https://replit.com/@espertusnu/TroubleWithAutoFormat

Yeah Idk, the format code button is very inconsistent. Sometimes it shows up. Other times it doesn’t.

But you can press Ctrl + S to format.

The format button appeared for me. If it doesn’t work, make sure your replit.nix file looks like this:

{ pkgs }: {
    deps = [
        pkgs.graalvm17-ce
        pkgs.maven
        pkgs.replitPackages.jdt-language-server
        pkgs.replitPackages.java-debug
    ];
}

If the formatting button disappears after that, run kill 1 in the shell and that should work.

Thank you, but Ctrl + S does not have any effect for me (Chrome/Windows).

I have tried everything you suggested, and nothing works. As far as I can tell, it doesn’t work for any of my (90) students.

This video shows me trying all of your suggestions.

Was the .replit file changed in any way in your repl? What happens when you create a brand new Java repl and try?

Do you have any browser extensions that could be getting in the way? If so, try disabling them + refreshing the workspace and see if the format button appears.

The formatting button is not present even if there are no extensions enabled. See video: replit-again.mp4 - Google Drive

And if it’s not on the tab, you’ll see an arrow. Click the arrow and you’ll see the format button.

Does the button appear when you use your browser normally? (not in incognito mode)

I just looked in java and it’s not there. It might be because java doesn’t have a web view. I know that all webview-lang’s have one, so that might be why.

If you watch the full video, you can see she tries that as well.

Here’s something I came up with that might fix the issue. Let me know if it worked for you!

Thank you. I created a new Java project, and my hidden files did have the references to jdt-language-server. I had not known about the new appearance of the formatter. The icon did show up in the Main.java tab, but it didn’t work. When I clicked on it, it spun for 10+ seconds without doing anything.

I then created another new project and ran jdt-language-server in the console, the icon showed up. Sometimes it works, but sometimes it spins without doing anything. Still, that’s major progress!

Are any of below warnings in the developer tools console significant?

I will share the console trick with my students

Unfortunately I’m not very familiar with java or the LSP server, so I’m not sure about the warnings.

If the formatter spins like that, try reloading the page or running kill 1 in the shell to force a repl reboot and see if it works.
