Not only is the build pipeline I save triggered, but all my others are triggered as well every time I edit the YAML of any of my pipelines. How might I make this not happen? It's inconvenient to have to manually stop all the running jobs that automatically are spawned by the saving of one of my many pipelines.
LATER ON: The "answer" below doesn't really answer the question. What I discovered is that the pipleline YAML is actually stored in the repository with the code it works on, so any change to a pipeline triggers all the pipelines triggered by changes to the repo. This is why ALL the pipelines then go into action. It's not what I want, but at least I understand it. I'm putting this here for anyone who stumbles across this via a search.
