This is because the package xcounter is not yet imported by the package metrics. We need to import the package xcounter in the package metrics as follows:21import "github.com/abc/metrics/xcounter"22type XCounter interface {23}

1I have a package for every part of my code, and I have a metrics package that does the same for metrics. I want to be able to use the same metrics package from any part of my code, but I don’t want to have to import it in every single file. I want to be able to just import the metrics package once in my main file, and then use it from anywhere in my code. I tried to do this by using a global variable, but it didn’t work. I also tried to use a package level variable, but that didn’t work either. I am not sure what I am doing wrong. I have been trying to figure this out for hours, and I am not getting anywhere. I am using go 1.10.32import (3var (4	XCounter = promauto.NewCounter(prometheus.CounterOpts{5	})6import (7func main() {8	fmt.Println("Hello, world!")9	metrics.XCounter.Inc()10}11import (12func main() {13	fmt.Println("Hello, world!")14	metrics.XCounter.Inc()15}16import (17var (18	XCounter = promauto.NewCounter(prometheus.CounterOpts{19	})
