• AttachMe will attach the IntelliJ debugger automatically even if you start your app from terminal (or any other way). You don't need to trigger Attach to process action manually.
• If you have a complex process hierarchy with many parent/child processes, AttachMe can auto-attach to all the newly forked child JVM processes. The behaviour will be similar to set follow-fork-mode child in the GDB debugger.

1. Download and install the plugin from the plugin marketplace. https://plugins.jetbrains.com/plugin/13263-attachme/

2. Start the AttachMe listener by going to Run > Edit Configurations > Add New. Then search for Attachme, select it, and run.

3. On the first run, the plugin will install a JVM agent jar and a bash configuration script in the $HOME/.attachme/ directory. To auto-attach the debugger, configure AttachMe like this:

source ~/.attachme/conf.sh

java com.example.MyApp # anything that runs on the JVM

Now you should see a new debugger window attached to the process and any of its child processes.

If you want to have custom JDWP or AttachMe port configuration, you can run it like this:

JDWP_ARGS="transport=dt_socket..." AM_PORT=9009 source ~/.attachme/conf.sh

java com.example.MyApp

You may have a problem with the bind address, which will manifest itself with this error:

JDWP exit error AGENT_ERROR_TRANSPORT_INIT(197): No transports initialized [debugInit.c:750]

To fix it, try to configure AttachMe with port address 127.0.0.1, like this:

JDWP_ARGS="transport=dt_socket,server=y,suspend=y,address=127.0.0.1:0" source ~/.attachme/conf.sh

AttachMe is not compatible with the JMX agent. If you are having problems running it with the auto generated SpringBoot run configuration, most likely disabling JMX will fix the problem.
