Spinnaker: property file vars from Jenkins triggers vs stages differ

TL;DR

In Spinnaker, read Jenkins property-file variables from the trigger when they came from a trigger, and from the stage context when they came from a stage. And if you run several Jenkins jobs in one pipeline, namespace your property files or the values will clobber each other. Context: From the official Spinnaker pipeline expressions guide.

Use this when you run into the situation in the title.

When not to use this skill: unrelated tasks. It covers only the procedure above.

Details

How you read a Jenkins property file depends on how it got into the pipeline: uploaded via a Jenkins trigger, its variables live under the trigger properties; uploaded in a Jenkins or Script stage, they land directly in the stage context and later stages read them from the stage context. The guide also warns that when multiple Jenkins jobs upload property files with the same variable names, they can overwrite each other.
