I read all the topic about gulp and heroku but I don't udnerstand what's wrong with my procfile.
When I'm in local launching like that works:
node node_modules/gulp/bin/gulp build
So in the procfile I write:
web: node node_modules/gulp/bin/gulp build
as advised here http://www.sitepoint.com/deploying-heroku-using-gulp-node-git/
But still this is not working. No build problem nothing with the heroku log...
Any idea ?

Im trying to host my object detection api on heroku but i can't due to it not recognizing my
Procfile, which is a file and not a text file. the way its spelled is Procfile, its contents are
web:gunicorn app:app
the way i know that its the Procfile thats the problem is because when i run bash and look at the root directory of the heroku git i see Procfile but when i look at the logs i see that no web process is running and on the dashboard the dynos is completely empty.
i've tried doing
web: gunicorn app: app instead of web:gunicorn app:app
to no avail, i've made sure that gunicorn is in the requirements.txt and know that its pip installing the requirements.txt as the cmd tells me that it is when i do git push heroku master. i've tried doing echo>Procfile and then modifying the contents of the file. i've tried both echo "web:gunicorn app:app"> Procfile and echo web:gunicorn app:app>Procfile i tried doing heroku ps:scale web=1 and get Scaling web dynos... failed ! No such process type web defined in Procfile. and when i do heroku ps i get nothing
I am trying to host a discord bot on Heroku (Discord JDA, Maven). I do this by connecting to Github and then deploying. The bot 'deploys' (view attachment) but doesn't actually work (view attachment).
What could I be doing wrong, or has anyone else come across a similar issue?
Quick and dirty way to deploy it:
You'll need to setup a Procfile, extensive info on that right here: https://devcenter.heroku.com/articles/procfile
The procfile is basically a file with no extension that tells the dyno how to execute your program.
A simple
worker: java $JAVA_OPTS -jar <PATH_TO_JAR>
will work fine if you don't need more config, refer to that link for more.
You can then deploy it like this (Good to have procfile and jar on the same directory):
$ heroku deploy:jar -a <YOUR_HEROKU_APP_NAME> --jdk <JDK_VERSION> --jar <PATH_TO_JAR> -i Procfile
Then to start it just do (Assuming you want a worker dyno, which is what discord should need)
$ heroku ps:scale -a <YOUR_HEROKU_APP_NAME> worker=1
Then stop it with:
$ heroku ps:scale -a <YOUR_HEROKU_APP_NAME> worker=0
I've found this is much simpler than using git, especially if you're doing tests or simple/quick stuff.
Possible solutions:
Set up a Procfile. A Procfile basically tells Heroku what command to run when your app is deployed. Inside the Procfile, write worker: node index.js. Also, make sure Procfile has a capital "P".
Set up package.json.
npm init
Then just skip through the set up and your file should be automatically created. IMPORTANT. In your package.json file, add your node and npm versions.
node -v
npm -v
Then go an type this in your package.json.
"engines": {
node: "your-version-here"
npm: "your-version-here"
}
Then try deploying your app to Heroku again. Also, make sure you have the "nodejs" buildpack set up for your app. Run it and test the discord bot.
I'm running my heroku app locally using heroku local web with this being the only line in my Procfile:
web:node index.js
How can I get it to print live logs while running locally?
I found this answer, but there are some things missing from that explanation, and I'm struggling with it, since I'm new to heroku. Any help is appreciated.
I have deployed my jar file to heroku using:
heroku deploy:jar <filename>.jar --app <appname>
Once deployed, how do I run the jar file with specific params, i.e. locally i would execute:
java -jar <filename>.jar <param1> <param2>
Am i using the Heroku service correctly? In essence I just need to run the Main command within the jar file and get the logs when completed.
Any help would be much appreciated.
heroku deploy:jar <filename>.jar --app <appname>
With this you essentially hardcorded:
jar <filename>.jar
Here is an example where you can configure parameters for your command
https://github.com/NNTin/shell-kun/tree/6b35e4b731bcf500366f60bbceafe076bf969fe1
Note: We are looking here at older software because HEAD no longer has it.
You need Procfile. app.json and the Heroku Deploy (see link in README.md) button are optional. They make deploying easier since you don't have to touch terminal/CLI.
Essentially you extend your Procfile to:
web: jar <filename>.jar $ARGS_AND_FLAGS
worker: jar <filename>.jar $ARGS_AND_FLAGS
web when you are utilizing a $PORT, worker when not.
Now you can modify your command by editing the environment variable ARGS_AND_FLAGS.
In this case the web process is activated and the worker process is deactivated.
After you changed your environment variable you can deactivate and then activate your process.
Create a Procfile in the same directory where you run heroku deploy:jar with the content:
web: java -jar <filename>.jar <param1> <param2>
and redeploy the app.
I have my github source here https://github.com/pramadae/Monkey and deployed it on heroku. And https://immense-harbor-7247.herokuapp.com/ is my heroku app link. Unfortunately I could not run my application. Please help me.
You should change your Procfile to:
web: gunicorn run:app
