It's not clear to me how to make this plugin report to different contexts in GH for each combination of a matrix/multiconfiguration job.
As I have it configured now, there is only one context for the whole job and each child job clobbers the status of the previous child job.
It seems like the Commit Status Context in the Build Environment for a [matrix] job needs to be able to substitute per-axis values into the context being reported. But I see no such facility.
Am I missing how this is done?
