# build bigdata bigtop components. This will take a while.
# Artifacts will be stored under individual component folder inside output folder.
#
# Example command line:
#   docker run --rm -u jenkins --workdir /ws -v ${PWD}:/ws \
#          bigtop/slaves:1.4.0-debian-9-aarch64 bash -l -c '. /etc/profile.d/bigtop.sh; ./gradlew deb repo'
#
# Note:
#   - User 'jenkins' is employed. It exists by default in the root docker image of bigtop/slaves.
#   - It's not allowed using 'root' to build bigtop. Some component refuses to be built in root.
#   - Image "bigtop/slaves:*-aarch64" will be retrieved from docker hub on live.
#   - bigtop.sh sets environment variables such as: JAVA_HOME, MAVEN_HOME, ANT_HOME, GRADLE_HOME, etc.
