Debugger broken without reason

• I confirmed that this is not an issue with the Eclipse JDT Language Server itself

What happened?

I was using the debugger without problems untile some hours ago using the remote debugger:

        jvmArgs = [
            "-agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=*:5005"
        ]

and a debug.json script:

[
  {
    "label": "Attach to Java app",
    "adapter": "Java",
    "request": "attach",
    "hostName": "localhost",
    "port": 5005
  }
]

now it returns error: "Debugger plugin is not loaded"

I've tried to reboot, relaunch, kill java, etc... but I can't find logs.

What did you expect to happen?

The debugger works.

Please check the following:

• is the debugger downloaded in the working directory of the extension? /local/home/<user>/.local/share/zed/remote_extensions/work/java/debugger
• do you have a custom JDTLS on your PATH?

Hi, hi don't have the remote extensions folder in my zed home:

This is my PATH:

/home/cristian/.bun/bin:/home/cristian/Jvm/amazon-corretto-23.0.0.37.1-linux-x64/bin:/home/cristian/.local/bin:/opt/maven/bin:/home/cristian/.local/bin:/home/cristian/.nvm/versions/node/v22.16.0/bin:/home/cristian/.cargo/bin:/usr/bin/flutter/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:~/.local/bin:/snap/bin:/opt/gradle/gradle-8.14/bin

Looks like we are not creating the debugger directory if it does not exist yet. Fix is on the way.

can I try to create it manually and relaunch something?

@sedax90 Yes, as a quick fix for you you could:

• find the extension workdir (on linux should be: $HOME/.local/share/zed/extensions/work/java)
• create a directory called debugger inside
• download this file: https://github.com/zed-industries/java-debug/releases/download/0.53.2/com.microsoft.java.debug.plugin-0.53.2.jar
• move it into that directory

That should do the trick as a workaround

Ok I've done, now after reopening Zed some folders was created:

but the error is still here:
error: "Debugger plugin is not loaded"

No, sorry the file should go into $HOME/.local/share/zed/extensions/work/java/debugger which you need to create
It's the folder you have but a subfolder within it

I confirm that it works, thanks
