Snaps to invoke external processes

[Eloy García (PC Actual)]

Hi Didier.

My snap package (wallpaperdownloader) invokes xdg-open internally but it
isn't working yet. Should I use a specific interface to accomplish that?
This is the snapcraft.yml

name: wallpaperdownloader
version: "2.3"
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
grade: stable
confinement: strict

apps:
  wallpaperdownloader:
    command: wallpaperdownloader.sh
    plugs: [x11, network-bind, 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:
    source: https://bitbucket.org/eloy_garcia_pca/wallpaperdownloader.git
    plugin: maven
    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


Thanks!!!

Best,

Eloy
