[aur-general] My -git package not updating

[Barnabás Béres]

Dear Arch users,
I have a big collection of wallpapers on gitlab. My friends suggested that
I submit it to the AUR. I have created a PKGBUILD according to
PKGBUILD-VCS.proto but my package doesn't update when I add a new
wallpaper to it on my gitlab. Here is my pkgbuild:
pkgname=nature-wallpapers-git pkgver=1.0 pkgrel=1 pkgdesc="Collection of
nature wallpapers" arch=(any) url="
https://gitlab.com/winux1/nature-wallpapers.git/" license=('unknown')
makedepends=('git') source=("git+$url") noextract=() md5sums=('SKIP') pkgver()
{ cd "$srcdir/${pkgname%-git}" printf "r%s.%s" "$(git rev-list --count HEAD)
" "$(git rev-parse --short HEAD)" } package() { cd "$srcdir/${pkgname%-git}"
install -d "${pkgdir}/usr/share/backgrounds/nature-wallpapers" install -m644
*.jpg "${pkgdir}/usr/share/backgrounds/nature-wallpapers/" }

What is wrong with it?
Thanks for your help in advance
