Hi James,
./gradlew bootRun --no-build-cache --rerun-tasks --info
> Task :classes
Skipping task ':classes' as it has no actions.
Resolve mutations for :findMainClass (Thread[#1615,Execution worker
Thread 4,5,main]) started.

Custom actions are attached to task ':findMainClass'.
Caching disabled for task ':findMainClass' because:
Build cache is disabled
Task ':findMainClass' is not up-to-date because:
Executed with '--rerun-tasks'.
There is neither a bootJar or bootWar task that will run. Skipping
finding main Application class.
Resolve mutations for :bootRun (Thread[#1615,Execution worker Thread
4,5,main]) started.
:bootRun (Thread[#1615,Execution worker Thread 4,5,main]) started.

I also create an example web application and converted it to a plugin
but as soon as I changed the build file with:
apply plugin: "org.apache.grails.gradle.grails-plugin" // added for plugin
It started the same issue.
Thanks again for looking into this.
Best regards,
Carl

Yes, so the task is not triggering for some reason. Can you run
‘./gradlew bootRun —no-build-cache —rerun-tasks’. Does it work then?

I hope this is what you were looking for.
Please let me know if I need to provide more.

support lazy. I've seen this occur before when the gradle cache
is cached. Can you please try running your build with '--info' on
it? Look for the 'FindMainTask' and see if it says 'FROM-CACHE'
or 'UPTODATE'. If you can confirm this and include the log
snippet from the find main task, I can help troubleshoot further.
