# for origin file refer to https://github.com/de-jcup/p2-updatesite-github-pages-automation

#
# How it works
# - JAR signing environment variables must be set
# - jar signing is done automatically
# - we use github pages to provide static content for eclipse marketplace
# - corresponding github repository is automatically calculated based on this repository
#   e.g. "eclipse-yaml-editor" will need a "update-site-eclipse-yaml-editor" repository
# - so by naming conventions this script can be used every where (in de-jcup github context.
#   if you want to use it with another user just set GITHUB_USER with other username
# - eclipse update site project must have "update" inside their project folder names (and we only accept ONE...)
# - The repository must exist on Github
# - The update site must be build before deployment
