Where are the daemon jar files located
I need the location of the daemon files and I need to update the -v of minecraft
Puffer panel doesn't copy the jar files like multicraft. Instead it's managed by downloads from the installation script. If you wish updating a jar take a look at the installation script (/srv/scales/lib/scripts/install/minecraft.sh).
I'm not sure exactly what you are asking for, but Scales is located in
/srv/scales. You can see this page for information on how to provide a different version parameter for Minecraft. http://www.pufferpanel.com/docs/adding-a-new-minecraft-server
