java - Run a .jar on Heroku -

i trying run .jar file on heroku, , can't find instructions anywhere on how this. have read wants me compile uploading heroku. possible, , if is, how this?

if helps, trying run minecraft craftbukkit server, , don't have pom.xml file yet.

you didn't provide details i'll try give , people reaches question way it.

first of all, create heroku account , create heroku application (assumed have done that).

second, need generate application jar , upload heroku. so, open terminal , install heroku cli (assuming unix terminal):

$ sudo npm install -g heroku-cli

you need have npm , nodejs installed, can check link: https://www.digitalocean.com/community/tutorials/how-to-install-node-js-on-ubuntu-16-04

once done that, can use npm update node version acceptable heroku-cli:

$ sudo npm install -g n $ sudo n 7.10.0

and run:

$ sudo npm install -g heroku-cli

in order deploy jars, need install deploy plugin:

$ sudo heroku plugins:install heroku-cli-deploy

than you're abble authenticate heroku-cli heroku credentials using:

$ heroku login

and run deploy command:

$ heroku deploy:jar path/to/target/myproject.jar --app you_heroku_app_name
