I am trying to write a simple grails 3.3.8 app that I would like to deploy to heroku.

I started with a simple grails app:

$ grails create-app example

I then added a Procfile:

web: ./gradlew bootRun -Dgrails.server.port=$PORT

And a stage task to build.gradle:

task stage(dependsOn: assemble)

I figure that this app does nothing, and therefore should not stress a 512M heroku dyno, however:

bootRun is for running and developing locally. Its optimized for quick development, not for running in production.

To run in production you would normally run 

./gradlew assemble
# Deploy build/libs/app.jar(or war) to your server
java -jar app.jar

There are many more ways to run a spring-boot/grails apps, for example deploying to tomcat or other servlet containers.
