What steps did you take:
I have used kbld as a library and kbld is detected as develop so if you have a minimumVersionRequired specified in kbld config.

What happened:
it failed with:

Validating config/ (kbld.k14s.io/v1alpha1) cluster: Parsing version constraint: Malformed version: develop

What did you expect:
To work fine.

Anything else you would like to add:
Chatting with @joaopapereira we made a change in vendored file vendor/carvel.dev/kbld/pkg/kbld/version.go with this code and worked as expected:

package version

import (
	"runtime/debug"
)

var (
	// Version can be set via:
	// -ldflags="-X 'carvel.dev/kbld/pkg/kbld/version.Version=$TAG'"
	Version    = "develop"
	moduleName = "carvel.dev/kbld"
)

func init() {
	Version = version()
}

func version() string {
	if Version != "develop" {
		// Version was set via ldflags, just return it.
		return Version
	}

	info, ok := debug.ReadBuildInfo()
	if !ok {
		return "develop"
	}

	// Anything else.
	for _, dep := range info.Deps {
		if dep.Path == moduleName {
			return dep.Version
		}
	}

	return "develop"
}

Environment:

• kbld version (use kbld --version): 0.41.0
