# Couchbase Spark Connector release script
# ========================================
#
# For internal use by Couchbase developers.
#
# Snapshot handling: snapshot builds are built locally, but not published to Sonatype, or Git-tagged.
#
# 1. Before running this script:
#  * Bump the version numbers in build.sbt and README.md.
#  * Push to Gerrit and get a review.
#  * Pull the changes again.
#
# 2. Now edit the Git SHA to tag. The version will be read from build.sbt automatically.

vers_sha=04a6fcd35aca87cf2c7bee3e790af7f3cb69f866  # the Git sha being released
vers=$(sed -n 's/^version := "\(.*\)"/\1/p' build.sbt)
if [[ -z "$vers" ]]; then
  echo "Unable to determine version from build.sbt"
  exit 1
fi

# 3. Now run the script from the script's directory, e.g.
#   cd couchbase-spark-connector
#   chmod +x release.sh
#   ./release.sh
#
# 4. After the script finishes successfully:
#  * Bump the version numbers in build.sbt for next SNAPSHOT.
#  * Push all changes to Gerrit for review, including changes to this file.
#  * Release on Jira.
#  * Release notes.
#  * Release the uploaded bundle via https://central.sonatype.com/publishing/deployments
