Jenkins: identify trigger type

Question

Is there a way I can identify the trigger for the current build during execution. What I want is to identify if the trigger was an SCM change, cron trigger or user trigger. I have multiple triggers defined for a job and want to use trigger type as a parameter in the shell execution script.

You can use the Rest API to get this info; here's an example:

http://jenkins.yourdomain.com/job/job_name/build_number/api/json?tree=actions[causes[shortDescription]]&pretty=true

returns

{
  "actions" : [
    {
      "causes" : [
        {
          "shortDescription" : "Started by an SCM change"
        }
      ]
    },
    {

    },
    {

    },
    {

    },
    {

    },
    {

    },
    {

    }
  ]
}

One solution is to use the Run Condition Plugin which can run a different shell script depending on the trigger type. It is not the perfect solution, but it will do what you want.
