Failure to Build During Debug Execution

Greetings,

IntelliJ is excellent, and I quickly switched from Eclipse.

In the recent development work, there is a Gradle multi-project that uses GitSubmodules:

SPF-----jpf-core (GitSubmodule)
           ---jpf-symbc

Building and running via CLI works without any issues.
Additionally, when I open the project root (SPF) and build jpf-core/jpf-symbc, it succeeds. 
However, when I attempt to debug the module within jpf-core that contains a main function, it fails.

Debugging via CLI is inefficient, and I would like to enhance efficiency by debugging with IntelliJ. 

Is there anyone who can identify the cause and solution for this?

Even if it's just a possibility, I would greatly appreciate your guidance.

IntelliJ Version: 2023.1.2/2023.2.1
JDK: 11 (Amazon Corretto)
Gradle: 8.2.1

Execution Module: jpf-core:RunJPF.main()'

CP: -cp SPF.jpf-core.main

Error: Cannot locate tasks that match ':jpf-core:RunJPF.main()' as project 'jpf-core' not found in the root project 'jpf-core'.
