Groups on permissions ex not working??

I really need help. There is a reason probably and I think my /pex command didn't work so I looked on youtube it said I had to change .yml to .jar, So I did. The command /pex now works but none of my groups I made are registered. Can anyone help me?? Also I CANT open the jar file. Here is whats in my permissions.yml folder groups:
