As the title, I added a new algorithm package in the plugin/pkg/scheduler/algorithm/priorities folder for Kubernetes. It is a folder, there are some Go source files, like the util folder. But, when run make, I got the errors:

test/e2e_node/e2e_node.test
    cmd/gke-certificates-controller

make: *** [all] Error 1

They are the Go files indeed, I didn't know the reason of the error. Or something else I missed?

And I just want to add my own algorithm package (not the third libs, such exapmle.com/xxx/xxx) into the priority, so what's the steps?

I referred to community/contributors/devel/godep.md and tried go build ./..., ./hack/godep-restore.sh, ./hack/godep-save.sh commands, but still did not work.
