Hey there !

Is it still possible to promote a build from a repo on a specific branch ? I saw [this comment](http://discuss.harness.io/t/manually-trigger-a-build/874/4) (EDIT: original comment deleted) but I am still unable to do it, I get `Incorrect Usage: flag provided but not defined: -branch`, and I didn’t see anything about this argument in [drone-cli/drone/build/build\_promote.go](https://github.com/drone/drone-cli/blob/master/drone/build/build_promote.go)

Thanks in advance !

Drone does not support `--branch` for build promotions. The referenced comment is unfortunately inaccurate.

Thanks for the answer ! Has this feature already been requested ?

I would like to use the promotion feature for deployment, but very often I have the usecase of deploying the application from a feature branch, and leave it in production for a few until actually merging with master.

The `drone build promote` feature promotes an existing build. When you push to your feature branch it will execute a Drone build. You can then promote this build, by build number, to the target environment. You can then promote the build, by build number, to production.

Ah yes that’s right absolutely ! Got confused for some reason, was running into errors because the version of the drone CLI I was using wasn’t matching the one from the server.

Thanks a lot !
