looks good in principle but I think the error case (e.g. not-readable or other io errors) is not handled well (true for the other check in this method, too)

pkg/kn/commands/plugin/handler.go

+		if runtime.GOOS == "windows" {
+			for _, ext := range []string{".bat", ".cmd", ".com", ".exe", ".ps1"} {
+				pathWithExt := pluginDirPluginPath + ext
+				if _, err = os.Stat(pathWithExt); !os.IsNotExist(err) {


What if err != nil but also !os.IsNotExist() is true ? (i.e. if there is an error as than not-found). The path is then returned nevertheless, which imo is wrong. (same error btw in the check above, too).

IMO this method should return (string,err) with an empy string if nothing is found, non-empty string if the plugin is found and err if any other error occured.

Also just split the os.Stat and os.IsNotExit to make logic clear

For now I've opted for less invasive solution that will only check err == nil to fix the reported issue. And also allow straightforward cherry-pick to release-0.13.

I agree that we should look closer to handler code and improve Lookup as suggested by @rhuss and anything else that will come up.

@dsimansk while we are at it, could you please also adapt the three lines above (just to be consistent) and add a comment that we should strive for a more sophisticated error handling in the future ?

Sure, will do.

thanks !

Before #682 it used to be almost immediate. This is because we now pass in the `DeletePropagationBackground` flag. I believe this is a mistake, not only because of the 20+ seconds of additional time to delete things, but IMO the CLI should talk to the server in the same way regardless of the --wait flag. That flag should just be a CLI thing to indicate if the user wants the CLI to wait for the server to complete but not HOW the server should do the delete.
