I am guessing that Pipeline jobs do not (or cannot) provide the capability to determine what jobs trigger them, but the FreestyleJob itself does not indicate (either on the build page or in the console output) that it triggered a PipelineJob.
Console Output looks as if nothing happened at all:
00:00:00.000 commit notification xxxxx
00:00:00.072 [EnvInject] - Loading node environment variables.
00:00:00.081 Building remotely on xxxxxx
00:00:10.452 No emails were triggered.
00:00:10.471 Started calculate disk usage of build
00:00:10.472 Finished Calculation of disk usage of build in 0 seconds
00:00:10.482 Started calculate disk usage of workspace
00:00:10.610 Finished Calculation of disk usage of workspace in 0 seconds
00:00:10.612 Notifying upstream projects of job completion
00:00:10.616 No emails were triggered.
00:00:10.616 Finished: SUCCESS
However, the downstream PipelineJob was correctly triggered.
Steps to reproduce:
- Create a parameterized pipeline job
- Create a freestyle job that triggers the pipeline job with or without parameters.
- Run freestyle job
- Review console log.
