How to delete a Artifactory build without artifacts? - artifactory

Question

We somehow managed to create a 'build' in Artifactory that does not have any artifacts (files) associated with it.
Through the web interface I only seem to be able to delete all builds for that particular release - which I obviously don't want.
Assuming we have 3 good 'builds' (has files etc.):
Moon -- 12.3 Build 23
Moon -- 12.4 Build 34
Moon -- 12.5 Build 89
and the aforementioned bad 'build'
Moon -- 12.0 Build 100
In the WebUI, 'Moon #12.0 Build 100' is listed in 'Last Deployed Builds' and also shows up as '12.0 Build 100' under 'Builds' for the 'Moon' release.
How do I delete the '12.0 Build 100' from Artifactory?
The WebUI seems to only allow deletion of all 'Moon' builds.
If the WebUI is a no go, how would I do so using the JFrog CLI or curl?
I am already having trouble coming up with the correct file spec to even find the 'build' - and obviously don't want to accidentally wipe out artifacts we want to keep.
{
"files": [
{
"pattern": "/api/build/Moon"
}
]
}
... doesn't return anything
{
"files": [
{
"pattern": "my-repo/Moon/*"
}
]
}
... returns all artifacts - but not the builds.
Thank you for any advice.

You can delete a specific build is using the delete builds REST API, for example
curl -X DELETE http://myserver:8081/artifactory/api/build/my-build?buildNumbers=100
In the upcoming version of Artifactory - 6.6, there will be a new option to delete a specific build from the UI (assuming you have the right permissions).
