You don’t specify why you don’t want to create extra job parameters, but if it
is to prevent users that run the downstream job from setting it when firing off
the build, then I would suggest using a combination of the Hidden Parameters
plugin and the Parameterized Build Trigger plugin.
The Hidden Parameters plugin would allow you to add a parameter in the
downstream job that you could set the name to UPSTREAM_TRIGGERED and set the
default value to FALSE. Users running the downstream job would not see the
parameter when they click the Build With Parameters Button, but the parameter
could be used say with a batch script or any other way a parameter is accessed.
Then use the “Trigger parameterized build on other projects” on your upstream
job and select Predefined Parameters. There you can add:
UPSTREAM_TRIGGERED=TRUE
So when it runs and triggers the job, it will set that parameter in the
downstream job to TRUE and you will know it was triggered by the upstream build.
You can also pass other defined parameters or environment variables such as
build number or job name by using the ${ParameterName} such as:
UPSTREAM_JOB_NAME=${JOB_NAME}
UPSTREAM_BUILD_NUMBER=${BUILD_NUMBER}
Just be sure the UPSTREAM_JOB_NAME and UPSTREAM_BUILD_NUMBER parameters are
added as a parameter, hidden or otherwise in your downstream job.
Hope that help.

Subject: Is there a way to pass environment variables from Upstream Job to a
Downstream Job without writing properties file to disk or creating extra job
parameters?
Hello,
I am trying to pass environment variables from Upstream Job to a Downstream Job
without writing properties file to disk or creating extra job parameters.
Basically, my Downstream job needs to know if it was triggered by upstream or
not.
Thanks!!
