When clicking on a certain Jenkins job, the title of the job starts with "Project". Suppose I have a job named "Demo Job", and clicking on the job itself will result in displaying "Project Demo Job". Is that a standard Jenkins way of assigning name to a job or it can be configured ?
Yes, it depends on the job that you configure.
Example :
If you create a freestyle project , then it would display Project <Your jobname>
If you create a pipeline project , then it would display Pipeline <Your jobname>
This would not impact anything and also when you access your jobname with ${env.JOB_NAME}
, then it would return you your jobname without appending anything.
