Trigger a Travis-CI rebuild without pushing a commit?

Question

Using Travis-CI, is it possible to trigger a rebuild without pushing a new commit to GitHub?

Use case: A build fails due to an externality. The source is actually co

Answer 1

Please make sure to Log In to Travis first. The rebuild button doesn't appear until you're logged in. I know this is obvious, but someone just tripped on it as well ;-)

Answer 2

You can do this using the Travis CLI. As described in the documentation, first install the CLI tool, then:

travis login --org --auto
travis token

You can keep this token in an environment variable TRAVIS_TOKEN, as long as the file you keep it in is not version-controlled somewhere public.

I use this function to submit triggers:

function travis_trigger() {
     local org=$1 && shift
     local repo=$1 && shift
     local branch=${1:-master} && shift

     body="{
             \"request\": {
               \"branch\": \"${branch}\"
              }
           }"

     curl -s -X POST \
          -H "Content-Type: application/json" \
          -H "Accept: application/json" \
          -H "Travis-API-Version: 3" \
          -H "Authorization: token $TRAVIS_TOKEN" \
          -d "$body" \
          "https://api.travis-ci.org/repo/${org}%2F${repo}/requests"
 }

I know you said without pushing a commit, but something that is handy, if you are working on a branch other than master, is to commit an empty commit.

git commit --allow-empty -m "Trigger"

You can rebase in the end and remove squash/remove the empty commits and works across all git hooks :)

Answer 4

I should mention here that we now have a means of triggering a new build on the web. See https://blog.travis-ci.com/2017-08-24-trigger-custom-build for details.

TL;DR Click on "More options", and choose "Trigger build".

Answer 5

If you open the Settings tab for the repository on GitHub, click on Integrations & services, find Travis CI and click Edit, you should see a Test Service button. This will trigger a build.

Answer 6

Simlpy close and re-open the PR if you do not have the write access.
