Download all dependencies with yumdownloader, even if already installed?

Hi,

I want to download all the dependencies with yumdownload even if it is installed on my computer.

for example if software package is already installed then it only download the given package and not all dependencies.

For example following command:

yumdownloader --resolve  nginx

only donwloads nginx package.

What is the command to download all dependencies?

I need command for Download all dependencies with yumdownloader, even if already installed?

Thanks
