How to debug a .jar file remotely using Intellij Idea

I am currently using intellij idea to code my project that I am working on, after creating of .jar file using OneJar command i deploy the .jar file on my linux server who address is something like 192.164.1.125.there I run the command sudo nohup java -jar fileName.jar & on server to start the jar file in the background and use the rest-client app to send rest calls to my .jar file.Whenever something goes wrong I can only see error message in nohup.out file and what I actually wanted is to debug my jar file using intellij idea i.e how can I debug my .jar running on 192.164.1.125 using intellijIdea running on my client machine.I know I have to use that EditConfigurations option in run menu of intellij and provide IP and Port, but how to do it exactly.

You can do the remote debugging on IntelliJ IDEA 2019.2 version very easily!

  • Click on "Run" -> "Edit Configurations"
  • Click on "+" and select "Remote"
  • Enter your remote IP and select source code folder path
  • Optional : change the name and port of your wish

enter image description here

  • Run your remote server jar with the command which is mentioned in the Command line arguments for remote JVM box . something like this,

    sudo nohup java "-agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=8911" -jar fileName.jar &

  • You are all set. add the breakpoints and click on Debug symbol to debug your remote jar from local

You must run the remote "java -jar .." command in debug mode by adding the additional magic flags. You can then tell your local IntelliJ to create a new debug configuration targeting a remote application - IntelliJ provides the magic flags you need.

The help page for this feature is at https://www.jetbrains.com/idea/help/run-debug-configuration-remote.html
