Detached steps don't get user-supplied parameters

I’m using a build step with detach: true and noticed my parameters are not being propagated to ENV. I verified this by printing out the ENV and comparing with detach: true and false. Using drone 0.8.

This is the expected behavior. Custom parameters are only passed to plugin steps. They are not passed to service steps or build steps. If a step is detached it is classified as a service, and not as a plugin.

If you want to pass custom parameters to a detached service, you can use the environment section:

    image: bar
    detach: true
      - A=B
      - C=D

Got it. Thanks.

This would be great to document at Shall I start a PR?
