# This workflow makes sure that a pull request does not make any incompatible changes
# to the public API of Gson
name: Check API compatibility
on: pull_request
jobs:
check-api-compatibility:
runs-on: ubuntu-latest
# This setup tries to determine API incompatibility only for the changes introduced by the
# pull request. It does this by first checking out the 'old' version and installing it into
# the local Maven repository before then using japicmp to compare it to the current changes.
#
# Alternatively it would also be possible to compare against the last release version instead.
#
# Both approaches have their advantages and disadvantages, see description of
# https://github.com/google/gson/pull/2692 for details.
