Today after successfully converting bosom to a Maven project I decided to deploy it in Heroku. I know two options:
This post followed the steps in the Heroku “WAR Deployment” article.
You can visit the deployed Heroku site in bosom2-war.
Steps
Prepare WAR file
Make sure that a WAR file is generated from our project. Generally it should be found in target/classes/<name-of-project>.war (bosom2-2.0.war in my case).
If there is none, then just run:
mvn clean install
Deploy the WAR file
> heroku war:deploy target/bosom2-2.0.war -a bosom2
Uploading bosom2-2.0.war
-----> Packaging application...
- app: bosom2
- including: webapp-runner.jar
- including: target/bosom2-2.0.war

▸ There was a problem deploying to bosom2.
▸ Make sure you have permission to deploy by running: heroku apps:info -a bosom2
> heroku apps:info -a bosom2
▸ Couldn't find that app.
This happend because Heroku will not create the applicatiom named “bosom2” like in the usual way. Instead, “bosom2” should be made manually in the website and try deploying again.

Remember that there was no Procfile mentioned in the official guide. It is because it is generated automatically and checking it in the website will show:
web java $JAVA_OPTS -jar webapp-runner.jar ${WEBAPP_RUNNER_OPTS} --port $PORT ./target/bosom2-2.0.war
Finally run the application:
heroku open -a bosom2
