Java

Remote Debugging

java -Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=5006 -jar <jar name>

or you can use

export JAVA_OPTS="-agentlib:jdwp=transport=dt_socket,server=y,suspend=y,address=5006"
java $JAVA_OPTS -jar <jar name>

Create a Remote run configuration:

1. Run -> Edit Configurations...
2. Click the "+" in the upper left
3. Select the "Remote" option in the left-most pane
4. Choose a name (I named mine "remote-debugging")
5. Click "OK" to save:

Start your application as you would normally, then in IntelliJ select the new configuration and hit 'Debug'.
