Google Cloud-Builder how to build all branches except for master

问题

I want to be able to build all branches that are not master, however when I try ^((?!master).)*$ the UI correctly shows all non-master branches but saving returns a HTTP 400 error.

{
  "error": {
    "code": 400,
    "message": "trigger_template branch_name is not a valid regular expression",
    "status": "INVALID_ARGUMENT"
  }
}

回答1:

this is stupid ... but works by ignoring everything that starts with "master"

^(?:[^m]|m[^a]|ma[^s]|mas[^t]|mast[^e]|maste[^r]|master.)

回答2:

The regex used must be compatible with Go's regex library, which this one is not. (It is compatible with JavaScript, which is why the UI works with it.) https://regex101.com/ is useful for playing with different language parsers. (A teammate just showed it to me.) Go's regex documentation is on GitHub.
