Jenkins:2.332.1, Parameterized Trigger

Hello, Experts

I am the freshman for the usage of the component “Trigger parameterized build on other project” (plugin:Parameterized Trigger)

I detected that:

  1. It will trigger two downstream jobs, like:
    Triggering a new build of xxx
    Triggering a new build of xxx
    then I have to self failed one of them to avoid the conflict
  2. the sub-feature of “current build parameters” seems not working.
    it can’t forward the parameters to the downstream jobs, even it seems to try to,
    maybe it is my fault that don’t know how to use it in downstream job.
    i called the parameters from upstream job by “echo ${parameters}” in the downstream job’s execute-shell

thanks for any help and comments
