Compile Spigot/Craftbukkit for 1.7.10

I have successfully installed MineOS and managed to setup a Spigot/Craftbukkit server.
But I want to setup a Spigot/Craftbukkit server for version 1.7.10.
On the BuildTools settings I see the oldest version is 1.8:

How do I compile Spigot/Craftbukkit for Minecraft 1.7.10?

Thanks in advance

There are multiple ways to go about this:

  1. compile spigot/craftbukkit via their tutorial and place it in your live directory OR

  2. adjust the filter line in the webui’s HTML

    remove_old_versions: 1.8 | (change this to below, which current hides all versions below 1.8)
    remove_old_versions: 1.7 |

Save and refresh your browser. It should now show all 1.7 profiles.
