Start intellij debugging from a script

I have 3-4 jvm processes which need to be attached for debugging. Every time I have to test a change in the code, I have to start-up jvm processes and click manually every jvm process's debug window to connect to the debugger. I want to automate this by firing a script which connects to jvm processes after starting them.

P.S: I start the jvm processes outside intellij.
