# GitHub Actions Workflow created for testing and preparing the plugin release in following steps:
# - validate Gradle Wrapper,
# - run test and verifyPlugin tasks,
# - run buildPlugin task and prepare artifact for the further tests,
# - run IntelliJ Plugin Verifier,
# - create a draft release.
#
# Workflow is triggered on push and pull_request events.
