Why can't I deploy my jar file on heroku?

Question

My version of Heroku is as follows:

heroku/7.0.60 darwin-x64 node-v10.2.1

When I run:

heroku deploy:jar ...

I get:

 ›   Error: deploy:jar is not a heroku command.
 ›   Perhaps you meant destroy
 ›   Run heroku help for a list of available commands.

This seems to contradict the docs:

https://devcenter.heroku.com/articles/deploying-executable-jar-files

What am I doing wrong?

Answer 1

I had the same Error, but the docs helped out. Before you can run the deploy command you have to install the java plugin: heroku plugins:install java

Answer 2

It means that you have not installed deploy plugin. So first install the heroku deploy plugin using below command:

heroku plugins:install heroku-cli-deploy

And then try to deploy the jar. It should work
