Hi, is there any way how to debug compile issues? I am trying to run ./gradlew :app:compileDebugUnitTestKotlin --debug and it always stuck with following message

2021-08-27T16:31:11.764+0100 [DEBUG] [org.gradle.cache.internal.DefaultFileLockManager] Waiting to acquire shared lock on daemon addresses registry.
2021-08-27T16:31:11.764+0100 [DEBUG] [org.gradle.cache.internal.DefaultFileLockManager] Lock acquired on daemon addresses registry.
2021-08-27T16:31:11.764+0100 [DEBUG] [org.gradle.cache.internal.DefaultFileLockManager] Releasing lock on daemon addresses registry.

I already identified test file which causing this issue but I don’t know what could be wrong and it is stuck forever.

You can debug compilation process by running any gradle task with following arguments:

./gradlew -Dorg.gradle.debug=true -Dkotlin.compiler.execution.strategy="in-process" <task-to-exectute>

After that you can attach remote debugger to port 5005

[dmitriy.novozhilov]

If you want to debug compilation inside kotlin daemon, then you need to kill all daemons and run new one with

./gradlew  -Dkotlin.daemon.jvm.options="-agentlib:jdwp=transport=dt_socket\\,server=y\\,suspend=n\\,address=5005" <task-to-execute>

All further invocations should be used without -Dkotlin.daemon.jvm.options (because daemon with opened port already started)
