[FIXED] How to convert curl -LO to a windows or groovy command?

Issue

I need to install kubectl on a windows node in Jenkins https://v1-19.docs.kubernetes.io/docs/tasks/tools/install-kubectl/

I don't have curl installed and I'd like to follow that exact step to install kubectl

curl -LO https://storage.googleapis.com/kubernetes-release/release/v1.19.14/bin/windows/amd64/kubectl.exe

Any suggestion? The other powershell command in that link doesn't work for me. Edit: As mentioned in my comment I tried:

Invoke-WebRequest "storage.googleapis.com/kubernetes-release/release/v1.19.14/bin/…" -OutFile "kubectl.exe

However the script just run and never stops The console just show:

[Pipeline] powershell

Solution

cmd + powershell

PowerShell.exe -Command "&{$ProgressPreference = 'SilentlyContinue'; Invoke-WebRequest https://storage.googleapis.com/kubernetes-release/release/v1.19.14/bin/windows/amd64/kubectl.exe -OutFile kubectl.exe}"

plain groovy

new URL('https://storage.googleapis.com/kubernetes-release/release/v1.19.14/bin/windows/amd64/kubectl.exe').withInputStream{
    new File('/.tmp/kubectl.exe') << it
}

groovy without withInputStream

def url = new URL('https://storage.googleapis.com/kubernetes-release/release/v1.19.14/bin/windows/amd64/kubectl.exe')
def stream = url.openStream()
new File('/.tmp/kubectl.exe') << stream
stream.close()
