Import Argo client library but build failed.

[fscnick]

Summary

Tried to utilize client library reference example/example-golang to fulfill our need. But build failed. Is something I did wrong? The snippet is from go.mod

	github.com/argoproj/argo v2.4.3+incompatible
	github.com/argoproj/pkg v0.0.0-20200102163130-2dd1f3f6b4de // indirect

Motivation

At the first, I encountered:

# k8s.io/client-go/rest
../../go/pkg/mod/k8s.io/client-go@v11.0.0+incompatible/rest/request.go:598:31: not enough arguments in call to watch.NewStreamWatcher
        have (*versioned.Decoder)
        want (watch.Decoder, watch.Reporter)

I googled and follows kubernetes/client-go#584 (comment)

Use go get k8s.io/client-go@master to upgrade client-go

After that, it came with another broken

# github.com/argoproj/argo/pkg/client/clientset/versioned/typed/workflow/v1alpha1
../../go/pkg/mod/github.com/argoproj/argo@v2.4.3+incompatible/pkg/client/clientset/versioned/typed/workflow/v1alpha1/workflow_client.go:63:32: undefined: serializer.DirectCodecFactory
# github.com/argoproj/argo/workflow/artifacts/hdfs
../../go/pkg/mod/github.com/argoproj/argo@v2.4.3+incompatible/workflow/artifacts/hdfs/util.go:21:10: options.KerberosClient undefined (type hdfs.ClientOptions has no field or method KerberosClient)
../../go/pkg/mod/github.com/argoproj/argo@v2.4.3+incompatible/workflow/artifacts/hdfs/util.go:22:10: options.KerberosServicePrincipleName undefined (type hdfs.ClientOptions has no field or method KerberosServicePrincipleName)

I referenced Gopkg.lock to specify go mod to download exact version mentioned in the file. It seems passed but now I got stuck at

# github.com/argoproj/argo/workflow/metrics
.dockerbuild/gopath/pkg/mod/github.com/argoproj/argo@v2.3.0-rc3.0.20200115233111-48b85e5705a2+incompatible/workflow/metrics/collector.go:72:54: too many arguments in call to prometheus.NewProcessCollector
        have (int, string)
        want (prometheus.ProcessCollectorOpts)

It had mismatched function arguments with our imports, we use v1.0.0. Instruct go mod to download old version seems useless, it would fresh to v1.0.0.

By the way, I change to master branch.

I have exactly the same problem (argo@v2.4.3). How do I fix it?
(I have the same mistake with master)

Finally, I took a workaround. The grpc client is what I wants, so copy the code related to grpc and it worked.

Finally, I've also found a solution which works...

github.com/colinmarc/hdfs v1.1.4-0.20180805212432-9746310a4d31 // indirect
github.com/argoproj/argo v2.3.0-rc3.0.20200115233111-48b85e5705a2+incompatible
