Is it possible to trigger Jenkins from one specific branch only?

Question

My situation is the following: I have three branches in a repo: master, dev and staging. And I have one job for each one of these branches, configured in 'Branches to build' section in Jenkins. origin/master, origin/dev, origin/staging.

Bitbucket triggers the job to build whenever there are changes to the repository via a repository hook .(https://confluence.atlassian.com/display/BITBUCKET/Jenkins+hook+management).

However, when I push to master, all jobs starts to build, and the same with the other two ones.

I want Jenkins "master" job to be built only when I push to master branch. Jenkins "dev" job to dev branch. Jenkins "staging" job to dev staging.

Is there a way to control this behaviour?

Answer 1

Did you set up polling?

https://wiki.jenkins-ci.org/display/JENKINS/Git+Plugin#GitPlugin-Pushnotificationfromrepository

... This will scan all the jobs that's configured to check out the specified URL, the optional branches, and if they are also configured with polling, it'll immediately trigger the polling (and if that finds a change worth a build, a build will be triggered in turn.) We require the polling configuration on the job so that we only trigger jobs that are supposed to be kicked from changes in the source tree.

Answer 2

I just discovered that Bitbucket does not allow to choose a specific hook when pushing to branches. It just calls all the hooks, then it starts all Jenkins' jobs.

My solution was to create a specific file on my machine, on which Jenkins is installed and set a Bitbucket hook to this file. (e.g. http://{jenkins url}:{apache port}/check.php)

Note that this apache port is not the same of Jenkins', but Apache's. In my case, Jenkins was running at 8080 and Apache at 7777. It did this to run php script, but not in Jenkins' directory.

Since Bitbucket hook sends a json file, I was able to verify in check.php which branch has been pushed on. Reference: POST hook management

After the verification using a simple 'if', I just called the right url to start the right job with exec_curl, like:

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, http://{jenkins url}:{jenkins port}/job/{job name}/build?token={job token});
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_exec($ch);
curl_close($ch);

And voilà.
