Hi everybody.
I’m having troubles building the snap for version 4.0 of my application WallpaperDownloader (Install WallpaperDownloader on Linux | Snap Store).
I’m on a new, fresh Ubuntu 20.04 and this is the snapcraft.yaml (which did run very well in past):
name: wallpaperdownloader
version: "4.0"
summary: Download, manage and change your favorite wallpapers from the Internet
description: WallpaperDownloader is a simple GUI Java based application for downloading, managing and changing wallpapers from the Internet
type: app
base: core18
grade: stable
confinement: strict
apps:
wallpaperdownloader:
command: bin/wallpaperdownloader.sh
# This extension is very useful for packaging GTK desktop applications using the new core18 base
extensions: [gnome-3-28]
# network-observe plug will be needed to run ping command from the snap
plugs:
- x11
- desktop
- desktop-legacy
- wayland
- unity7
- network-bind
- network-observe
- home
- gsettings
parts:
# Pulls the code from the original source (master branch)
# desktop-gtk3 is a snapcraft part (snapcraft-desktop-helpers) from the Wiki: https://wiki.ubuntu.com/snapcraft/parts
# It enables desktop integration and gsettings manipulation from the confined application
# It is necessary to use gsettings interface (see above) in order to have a fully functional
# desktop-gtk3 part
# Github repository for snapcraft-desktop-helpers: https://github.com/ubuntu/snapcraft-desktop-helpers
wallpaperdownloader:
plugin: maven
source: https://bitbucket.org/eloy_garcia_pca/wallpaperdownloader.git
source-type: git
source-tag: master
stage-packages:
# mate-desktop-common is necessary to have MATE gsettings schemas available for the application
- mate-desktop-common
#after: [desktop-gtk3]
# It will copy wallpaperdownloader script into /bin/
# This script contains all the commands needed (sets env variables, launches the jar file...) to
# execute the application
exec:
plugin: dump
source: scripts
source-type: local
This is the directory from I run snapcraft command once the repo is cloned https://bitbucket.org/eloy_garcia_pca/wallpaperdownloader/src/master/snap/
Everything is fine until it tries to build gnome-3-28-extension. This is the error:

Verify that the part is using the correct parameters and try again.
Run the same command again with --debug to shell into the environment if you wish to introspect this failure.
Do I need to change something in the snapcraft.yaml? It was running smoothly in previous versions.
Thank you very very much
