Gmad File List verification failed

I dont know why but every time i try to make my addon I get that same error.
I do have the addon.json


{
	"title"		:	"Stalker Seva Playermodels",
	"type"		:	"model",
	"tags"		:	[ "fun", "roleplay" ],
	"ignore"	:
	[
		"*.psd",
		"*.vcproj",
		"*.svn*"
	]
}

But I just dont know why it wont work.
