How to trigger a Jenkins Remote job using pipelines in BitBucket with parameters

So I have a situation where I need to trigger a simple job for calculating data on a package. BitBucket pipelines take too much time to complete so it was a good idea to place that job on external Jenkins server. Information that this job requirement is a ${bitbucket_commit} and this needs to be passed through. Forget Webhooks.

Pre-requirements:

1. Jenkins Server
2. Access to a Bitbucket repository

Steps:

1. Install two plugins to a Jenkins server that would allow triggering anonymously a job:
   • https://plugins.jenkins.io/build-token-root/
   • https://plugins.jenkins.io/build-token-trigger/
2. Create a job inside a Jenkins.
   • Enable a Build Trigger
     
     
   • Make build parametrised
     
     
   • Execute shell Commit
     
     *Downloading repository archive notes:
     Use short (12 characters) version of commit_hash in BUILD script if you need to download zip file etc like https://bitbucket.org/<COMPANY>/<REPOSITORY>/get/<COMMIT_ID::12>.zip (you can use a long hash to download but after unzip folder would be in short hash )
     EDIT: $(echo $COMMIT_ID | cut -c1-12)
     
3. Make sure your BitBucket can speak with your Jenkins ( Firewall )
4. Create a pipeline inside BitBucket /bitbucket-pipelines.yml

pipelines:
default:
   - step:
      name: Trigger Build
      script:
         - curl "https://<YOURJENKINS>.com/jenkins/buildByToken/buildWithParameters?job=<YOUR JOB NAME>&COMMIT_ID=${BITBUCKET_COMMIT}&token=<YOUR TOKEN>"
