downloadUrls.go

package main

	"fmt"
	"os"
	"strings"

	"github.com/sonatype-nexus-community/gonexus/rm"
)

func main() {
	rm, err := nexusrm.New("http://localhost:8081", "admin", "admin123")
	if err != nil {
		panic(err)
	}

	components, err := nexusrm.GetComponents(rm, os.Args[1])
	if err != nil {
		panic(err)
	}

	mainAsset := func(assets []nexusrm.RepositoryItemAsset, ext string) string {
		for _, a := range assets {
			switch {
			case strings.HasSuffix(a.DownloadURL, ext):
				return a.DownloadURL
			}
		}
		return ""
	}

	for _, c := range components {
		fmt.Println(c.Name)
		switch c.Format {
		case "rubygems":
			fmt.Printf("\t%s\n", mainAsset(c.Assets, ".gem"))
