Unfortunately, all the prevoius answers are incomplete. I've spent much time to find the correct way of remote debuging in IntelliJ and here is the full explanation.

We assume that the project code is in your local machine (Windows OS) and you have a deployment of your project on an Ubuntu VM in your server (or your VMWare workstation). and these two machines are in the same network (they can ping eachother)

First of all, add the a new Run/Debug configuration using the menu Run>Edit Configuration and then hit the + button at the top left corner and choose the "Remote" option. Keep the configuration parameters as is and just define a name for your new config.

Secondly, open putty and connect to your remote server over SSH. run below command to add remote debugging feature to your project in the putty terminal:

export JAVA_OPTS="-agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=5005"

Now change to your project's root directory on the remote server (in the same putty session) and run it using the command you usually use to do it (mine is as following for example):

mvn -U clean spring-boot:run

Here comes the most important part that everybody neglected here :)

Right click on the top of the putty session window and select "Change Settings.." option. Go to the path Connection>SSH>Tunnels in the left side options tree. Now add two port forwarding records such as the following picture (one Local, which forwards the localhost 5005 port to your remote server IP with the same port number, and one Remote who forwards the remote 5005 port to the 5005 port on localhost machine)

Finally go back to IntelliJ and from the run menu choose your previously added configuration and then hit the Debug button. Your local IntelliJ IDEA should be connected to the remote deployment of your project now, ready to debug!!
