prometheus: promql Go import problem: use of vendored package not allowed

What did you do?

I’ve tried to import the github.com/prometheus/common/model package so I can construct a promql.AlertStmt from scratch. Here is the demo code that I’m using:

package main

import (
    "github.com/prometheus/common/model"
    "github.com/prometheus/prometheus/promql"
)

func main() {
    _ = &promql.AlertStmt{
        Annotations: model.LabelSet{},
    }
}

Building this package is not possible because promql uses a vendored package and thus I’ve got this error:

./demo.go:10: cannot use "github.com/prometheus/common/model".LabelSet literal (type "github.com/prometheus/common/model".LabelSet) as type "github.com/prometheus/prometheus/vendor/github.com/prometheus/common/model".LabelSet in field value

This is ok, because they really are two different packages (one is vendored, and the other one is pulled by me and put into GOPATH), but if you go and use the vendored import path:

package main

import (
    "github.com/prometheus/prometheus/promql"
    "github.com/prometheus/prometheus/vendor/github.com/prometheus/common/model"
)

func main() {
    _ = &promql.AlertStmt{
        Annotations: model.LabelSet{},
    }
}

Now you get the error:

package demo
    imports github.com/prometheus/prometheus/vendor/github.com/prometheus/common/model: use of vendored package not allowed

What did you expect to see?

I want to be able to create a custom promql.AlertStmt with the Annotations field

What did you see instead? Under which circumstances?

As described above, it’s not possible to create such a value
