Help on my minecraft plugin!!

So, im making a minecraft plugin for my server. And im having a bit of trouble, I want it so that when you do the command (map1) it will create a new world/Just copy the map so its the same always through multiverse and then teleport you to it. But ive only made it so it teleports you to coordinates. Any help? :/
