Debug a Gradle Build

https://docs.gradle.org/current/userguide/troubleshooting.html#sec:troubleshooting_build_logic

External Gradle Process

Gradle Process Instrumentation

Use -Dorg.gradle.debug=true. Experimented with Gradle 6.8.3.

./gradlew -Dorg.gradle.debug=true --no-daemon <task-to-debug>

Even if --no-daemon was specified, Gradle will issue a message similar to:

To honour the JVM settings for this build a single-use Daemon process will be forked. See https://docs.gradle.org/6.8.3/userguide/gradle_daemon.html#sec:disabling_the_daemon.
> Starting Daemon

and will stop there waiting for the debugger to attach. The JVM will listen on 5005.

If you need to use a Gradle daemon, the daemon JVM can also be instrumented to start in debug mode:
