Combine spans from Gradle into a parent Jenkins trace

[jacob-bresciani-everbridge]

I'm looking at using this plugin but having the gradle build triggered from a Jenkins job which is using the Jenkins opentelemetry plugin. Unfortunately this results in a trace for the Jenkins job and a separate trace for the gradle task. Is it possible to have the gradle spans show up in Jenkins job's trace?

Hi @jacob-bresciani-everbridge I wrote this as a proof of concept. Feel free to do with it as you please. :)

I'm guessing you'd want to figure out some way to propagate the trace from whatever jenkins is doing, and pick it up using a propagator at the beginning of the process, but I'm not familiar with how the jenkins plugin works, so you'd have to figure that bit out, I think.

Just FYI, this code is super out of date with the OpenTelemetry libraries; I have no idea if it even works any more. :)

ha, good to know, it still works with the current collector just fine btw.

I'd be very happy if someone wanted to take ownership of this and contribute to the opentelemetry-java-contrib repo... I don't have the bandwidth to manage it, though.
