This is caused by depending on k8s.io/kubernetes directly as a library, which is not supported. The components intended to be used as libraries are published as standalone modules like k8s.io/api, k8s.io/apimachinery, k8s.io/client-go, etc, and can be referenced directly.

[chinglinwen]

for the go module it just fail, because k8s pkg official says k8s.io/kubernetes is not supported for outside use.

kubernetes/kubernetes#90358 (comment)
This is caused by depending on k8s.io/kubernetes directly as a library, which is not supported. The components intended to be used as libraries are published as standalone modules like k8s.io/api, k8s.io/apimachinery, k8s.io/client-go, etc, and can be referenced directly.

after many try, I observe it failed for go1.18, so I re-install go1.14 (before go module), it works now by ./build.sh .
