Ah. It wants the program git installed. Git downloads the source code properly. In this case its wanting Bukkits source code (will probably want Sponges too).
https://git-scm.com/downloads
When installing make sure that PATH is ticked
Well I think now that Sponge is missing?

Your missing the Grief Defender API. If you download it and extract it inside the grief defender source code that should work.
It should come out as a folder
Ah the folder was empty… I donwloaded, rerun and now…

If you run the gradle build command inside the grief defender api it should fix that issue (assuming nothing goes wrong)
well when I do that in the API folder it works, but create that the plugin? cause when I try after the building part in the API folder, the normal folder it crash again 
What the error in the normal one?

thats the Error when I do the Command back again in the Normal Griefmaster Folder and not inn the API folder
I decided to try and build it myself. Found that some of the gradle files arnt right.
So I decided to fix them and send you the details 
The easiest thing to do is delete the “bukkit” folder in the grief defender folder (stops it building Bukkit (which is the error you reported).
Next up. The file of “build.gradle” within the “Sponge”, open that file with something like “Notepad” (All windows computers have it) and replace the text with this text. After that it worked for me.
The plugin file is in “/sponge/build/libs/”
