How to start JanusGraph with debug?

[qDonl]

I have a program embedded in JanusGraph. This program was started by JanusGraph, I want to remotely debug through IDEA, but I don’t know how to start JanusGraph in debug mode.
I want to start JanusGraph like a JAR.

java -Xdebug -agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=9999 -jar myjar.jar

but i don;t know how to start janusgraph with debug.

Please show detailed commands, thx!!!

It seems you follow the tutorial: https://www.jetbrains.com/help/idea/tutorial-remote-debug.html
This tutorial already gives detailed instructions how to start your application jar. When trying this, what happens?
Note that your application jar uses embedded janusgraph, so janusgraph with its dependencies should be on the classpath. Do you use maven to specify dependencies for your application?
