How do you enable debug builds for a project? I don't have the "Debug Build" button. Thanks!

@aryairani you have to do the following for public repos:

curl -s -X POST \
  -H "Content-Type: application/json" \
  -H "Accept: application/json" \
  -H "Travis-API-Version: 3" \
  -H "Authorization: token ********************" \
  -d "{\"quiet\": true}" \
  https://api.travis-ci.org/job/${id}/debug

where the *** is for the token that you get from travis login

you could also do

curl -s -X POST \
  -H "Content-Type: application/json" \
  -H "Accept: application/json" \
  -H "Travis-API-Version: 3" \
  -H "Authorization: token ${travis token}" \
  -d "{\"quiet\": true}" \
  https://api.travis-ci.org/job/${id}/debug

to get it and then the job id you can do travis open using the cli and then click the config option and then from the url:

https://travis-ci.org/packtci/multiple-languages/jobs/399353693/config

you grab the value 399353693 and then we make the following call:

curl -s -X POST \
  -H "Content-Type: application/json" \
  -H "Accept: application/json" \
  -H "Travis-API-Version: 3" \
  -H "Authorization: token ${travis token}" \
  -d "{\"quiet\": true}" \
  https://api.travis-ci.org/job/399353693/debug

I have obtained my token from the website: https://travis-ci.org/ --> Profile --> Settings and used it with the following request:

curl -s -X POST \
   -H "Content-Type: application/json" \
   -H "Accept: application/json" \
   -H "Travis-API-Version: 3" \
   -H "Authorization: token <my_token_goes_here>" \
   -d "{\"quiet\": true}" \
https://api.travis-ci.org/job/<my_job_id>/debug

This is the response I get:

{
  "@type": "error",
  "error_type": "wrong_credentials",
  "error_message": "access denied"
}

Is there anything else I need to do? Is there any authorization needed to access the API with my token?

When doing a restart instead of debug my token is accepted:

{
    "@type": "pending",
    "job": {
        "@type": "job",
        "@href": "/job/448444292",
        "@representation": "minimal",
        "id": 448444292
    },
    "state_change": "restart",
    "resource_type": "job"
}

Thanks

Instead of opening up your travis.yml file and copying commands from there, Travis has provided several bash functions that run these commands:

travis_run_before_install
travis_run_install
travis_run_before_script
travis_run_script
travis_run_after_success
travis_run_after_failure
travis_run_after_script

For public repos, you must first email them support@travis-ci.com asking them to turn on debug mode for that repo.

@brandondrew Thanks. That was what I was looking for.

@MasterOdin Thanks for clarifying this. I was under the impression that emailing travis was an optional method to enable debug build and the other method was to use the API.

@smac89 the easier route is (if you're able) to temporarily make the repository private and then go to Travis CI -> Settings -> Sync account (need to smash that button a couple of times to register your intent).
The Debug Build/Job button should then be available.
