Build Pack Error when deploying dokku about heroku-buildpack-java HOT 8 CLOSED

I was using the wrong URL for the buildpack.
Insted of usng the url in the command below
dokku config:set myapp BUILDPACK_URL=https://github.com/heroku/heroku-buildpack-java/releases/tag/v66

I changed for
dokku config:set myapp BUILDPACK_URL=https://github.com/heroku/heroku-buildpack-java.git

I'm now being able to deploy again. :)

Thank you @jkutner for following this with me. :)

from heroku-buildpack-java.

@devjsaon it looks like you might be using an old version of the buildpack--there is no line 43 in the current version of the Java buildpack.

Can you confirm that you're running the latest code in the master branch of this repo?

hi @jkutner

thanks for you quick reply. :)

Yes I'm using old version of buildpack.
I added the following line to my procfile to force specific version of buildpack.

dokku config:set myapp BUILDPACK_URL=https://github.com/heroku/heroku-buildpack-java/releases/tag/v33

and then I've tried to deploy again and I see same error.

Can you use a newer version of the buildpack? v33 is almost 5 years old now.

from heroku-buildpack-java.

Yes I can, the point is how do I do that?
Before the problem, my procfile had only 1 line. - the one below
web: java -jar target/*.jar -Dserver.port=$PORT --spring.profiles.active=deploy
But since my deploys started to fail, I decided adding it in a try to resolve the problem.
I'm open to any suggestion or change.

from heroku-buildpack-java.

I think you update the buildpack by running:

$ dokku config:set myapp BUILDPACK_URL=https://github.com/heroku/heroku-buildpack-java/releases/tag/v66

(note the v66)

from heroku-buildpack-java.

and the command will be inside my procfile, right?

from heroku-buildpack-java.

After running the config set from my ubuntu machine I'm still getting error.
