Seems like jdb doesn't work with maven. Everything I look up online is talking about debugging maven through Eclipse or IntelliJ. I'm literally just making this project through UNIX with maven. Normally I could debug using println or something but this is my first multi-threaded project and I have no idea where to start. Just want to step through the program line by line.

It sounds like you want to use mvnDebug to execute instead of just mvn, this will run in remote debugging mode. Then connect to the port from another terminal window while the program is running with jdb jdb -attach 8000 (this is the default port, it should print in the console what it's actually using)

  • So when it says "Listening for transport dt_socket at address: 8000", I should enter the command "jdb -attach 8000"? It doesn't seem to do anything – NoClue Dec 27 '18 at 00:54
  • What output do you get from the 2 terminal windows? It sounds like the first one is starting the debugging session, is it terminating before the connection? – Adrian Visan Dec 27 '18 at 01:13
  • Sorry I misread your original post and was only using one terminal window. Works now, thanks! – NoClue Dec 27 '18 at 01:21

    My original post didn't contain the info about the separate terminal, I realised that and updated afterwards. My apologies for not giving a comprehensive answer on the first try. Glad to have been of help in the end. – Adrian Visan Dec 27 '18 at 01:30
