We have some Java code that starts a new process using the following code:
Runtime.getRuntime().exec(command); I’d like to be able to tell the debugger that it should follow the child process like you can do with GDB as documented here by issuing the
set follow-fork-mode child command.
Is there something equivalent in the IntelliJ IDEA Java debugger? If so how do I configure it?
Java doesn’t provide an automated way to debug processes and their child processes. One needs to run the child process with the JVM options to enable debugging. IDEA Remote Debug configuration will suggest the proper options to use. Once the process is started with the appropriate options you can connect to it from IDEA with the Remote Debug configuration.
You may want to start with
suspend=y so that the execution is suspended until you connect with the debugger.
