# Builds and deploys the site if the build was successful
# This job builds the website and deploys the build artifacts to the 'content' directory
# Any additional files that are not part of the site build but should be published (e.g. website configuration files) must be handled explicitly
# See step "Move additional resources to build directory" and sub-steps "Dropping old site resources" and "Adding new site configuration" of the 'publish' step

# Conditions necessary to trigger a build
# Only run for pushes to the following branches
# Including the branch that is pushed by this action will lead to an infinite loop
- 'master'
# Only build if a file in one of these paths has been changed
- 'src/main/asciidoc/**'
- 'src/main/template/**'
- '.asf.yaml.publish'
- '.htaccess'
