使我的JAVA（jar）程序在Heroku上运行

Question

I have made a bot in Java and it works great when I run the command:

heroku run nohup java -jar bot.jar

However, after 24h Heroku closes it because of their Dyno policy. So, I thought of making a Procfile in order for it to execute the command above everytime it comes alive again.

I've tried placing the following commands inside the Procfile :

worker: java -jar bot.jar
worker: nohup java -jar bot.jar

And I even made a run.sh file that contains:

#!/bin/bash
nohup java -jar bot.jar

In order to make a Procfile that has:

worker: sh run.sh

Sadly, none of this works, because everytime the Dyno executes the Procfile (right after I push a new version of it through git), the bot never comes alive. The logs show:

I have no idea what to do in order for my bot to run from the Procfile . Can you help me?

Thanks.

Try running:

$ heroku ps:scale worker=1

This will ensure that one worker process is always running.
