Why does the error "Could not find application!" occur? when deploying Java to Heroku?

Question

Java

At the last stage of deployment I get an error:

Could not find application! Make sure you configured your application name correctly.

After that - BUILD SUCCESS, but the application does not work, the answer to the open command is that it Couldn't find that app.
In what there can be a hitch, prompt, please.
I do everything according to the Heroku instructions: https://devcenter.heroku.com/articles/deploying-ja...
Thanks in advance!

Answer 1

The port is randomly selected when the application starts. Please check the port you received in the application with the port which is in the environment.
