well simply this is what i am getting;

 sa@sa-VPCW11S1E:/opt/hubot/bin$ heroku buildpacks
 === young-everglades-12415 Buildpack URL
 heroku/java
 sa@sa-VPCW11S1E:/opt/hubot/bin$ sudo git push heroku master

 sa@sa-VPCW11S1E:/opt/hubot/bin$

although i did set a buildpack on the app git push failed because no buildpack detected ?

How can i resolve this, and is it actually the right steps towards deploying hubot ?

The heroku build packs still use the detection script to identify the language in use. Since Hubot is not a java project and it looks like you are using the java build pack, I suspect the detection script failed.

To fix this, try removing the buildpack.

% heroku buildpacks:remove heroku/java

After this I would try, 

% git push heroku master

(Optional) I believe the rediscloud addon is needed for some scripts. You can add it with,

% heroku addons:create rediscloud

Then watch the logs heroku logs and see what happens.

There is a good deployment guide in hubot/deploying/heroku.md

  • as you suggested i did remove the buildpacks, and tried to create rediscloud but unfortunately i am facing another dilemma which is verification. everytime i try to use the command to create reidcloud or even from the browser heroku dash bord addons i get the request to verify my account with a credit card ? is there a way around this ? – madnomad10011 Nov 13 '16 at 23:57
  • Sorry, not that I know of. Maybe skip that step and see if you can get it deployed without it? – HParker Nov 14 '16 at 00:16
  • Still getting the same error no default lang. detected ? – madnomad10011 Nov 14 '16 at 11:59
  • all right, well i solved the git push heroku master by adding redis addon with command heroku buildpacks:add -i 1 https://github.com/heroku/heroku-buildpack-redis.git and then git push heroku master. Now what is the next step to interact with hubot >? – madnomad10011 Nov 14 '16 at 12:15
