How to solve H14 error in Heroku?

Question

I am trying to deploy war file using spring boot app usng maven plugin in heroku.

The error code that I am getting on deploying it is:

2018-03-10T05:47:07.563714+00:00 heroku[router]: at=error code=H14 desc="No web processes running" method=GET path="/favicon.ico" host=patiyati.herokuapp.com request_id=ebb35d7d-1fff-484f-8f58-faccd506b002 fwd="171.76.43.17" dyno= connect= service= status=503 bytes= protocol=https

        </plugins>
    </build>
</project>

I have gone through many similar questions and have tried implementing those but none was of use... On using Heroku ps:scale web=1 -a patiyati I get "Couldn't find process type error"

I followed the steps given in the document heroku deployment using maven plugin, but it provides me the same result.

On adding a procfile :

web: java $JAVA_OPTS -cp target/classes:target/dependency/* com.spring.app.SpringBootWebApplication

Where SpringBootWebApplication is my main class and is under com.spring.app package.

Now i get app crash as a result

2018-03-10T08:31:39.460117+00:00 heroku[router]: at=error code=H10 desc="App crashed" method=GET path="/favicon.ico" host=patiyati.herokuapp.com request_id=59d88594-c17f-4003-8527-722d780f475c fwd="171.76.43.17" dyno= connect= service= status=503 bytes= protocol=https

It would be great if anybody could help me solve this issue. Thanks in advance.

Answer 1

I had same problem. I removed <packaging>war</packaging> line from pom.xml then pushed and it started working. I hope it helps someone

Answer 2

Add a Procfile in your application root directory with below entry and push the app.

web: java -jar $JAVA_OPTS -Dserver.port=$PORT target/your-app-name-version.jar

EDIT

Just realized from your pom.xml that you're packaging as war. Please refer here on war deployment to heroku.
