Gmad "json error: couldn't find file"

[majorrr]

When i use gmad to get a .gma file I keep getting this error and I dont know why:
C:/Users/majorrr/Desktop/weapon_MajorrrsAdminGun-out/addon.json error: Couldn't find file

my addon.json file contains this code:
{
"title" : "Majorrr's Admin Pistol",
"type" : "weapon",
"tags" : [ "roleplay", "fun" ],
"ignore" :
[
"*.psd",
"*.vcproj",
"*.svn*"
]
}

this is the path to the .lua weapon file and addon.json file:
\weapon_MajorrrsAdminGun\lua\weapons\shared.lua
with
\weapon_MajorrrsAdminGun\addon.json

please note I am new to Glua so please be easy on me!

It's in the error pal:

Your file

\weapon_MajorrrsAdminGun\addon.json
vs the error

C:/Users/majorrr/Desktop/weapon_MajorrrsAdminGun-out/addon.json
