How to use parallel steps?

Question

Here's a subsection of my bitbucket-pipelines.yml:

pipelines:
branches:
release:
            - parallel:
                - step: *BuildWindows
                - step: *BuildMacOS
                - step: *BuildDocumentation
            - step:
name: Upload
deployment: Develop

This setup is intended to have builds running on three machines/platforms simultaneously. (Documentation is built on linux)

The definitions for these steps each target a different self-hosted machine that is currently idle like so:

definitions:
steps:
        - step: &BuildWindows
            name: Build Windows
runs-on:
                - 'self.hosted'
                - 'windows'

This page states that free plan users can have up to 10 parallel steps: https://support.atlassian.com/bitbucket-cloud/docs/parallel-step-options/

In my experience, these steps execute sequentially. Any idea what i might be doing wrong? I have run out of build minutes (trying qodana), but since these steps run on self.hosted runners that should be fine, sequential builds to work.

No errors, the pipeline runs through to completion, just one step at a time.

Were you getting some errors?

Hi @Mark C @Aron Gombas _Midori_ , thanks for your suggestions.

Unfortunately neither of them work. I've waited for build minutes to reset. All runners are online ready to accept steps. I have added the steps indirection to the parallel section.

I see BuildWindows starting right away, Build macOS and Build Documentation stay queued until their previous step is done.

Here is my full bitbucket-pipelines.yml: https://pastebin.com/8h5hHHqT

I'm trying to execute the branches -> release pipeline

Any other ideas as to what i could be doing wrong? The bitbucket pipelines yaml validator sais it's valid.
