Changes to the parameter defaultValue in Jenkinsfile are not reflected in existing Jenkins job after executing the job.
- use following parameter definition:
- add new job and run it for the first time, go to job configuration - the job should now have this parameter with "pattern' default value
- change in the Jenkinsfile pattern to "pattern2"
- run the job again and go to job configuration - the job will still have the old value "pattern"
