quick build

./mvnw -T2C clean install -nsu -DskipTests -Dmaven.javadoc.skip=true -Dmaven.source.skip=true -Dair.check.skip-all=true -pl '!:trino-server-rpm,!:trino-docs,!:trino-proxy,!:trino-verifier,!:trino-benchto-benchmarks'
run Trino in a container, quickly

docker rm -f trino; docker run --rm -it --name trino -p 8080:8080 trinodb/trino:438
run static code analysis

# checkstyle only
./mvnw -T2C checkstyle:check@checkstyle

# all verifications, including Eerror Prone compiler
./mvnw clean verify -DskipTests -Dmaven.javadoc.skip=true -Dmaven.source.skip=true -Dskip.npm -Dskip.yarn -nsu -P errorprone-compiler -pl '!:trino-server,!:trino-server-rpm,!:trino-docs'
quick build antlr grammar alone

./mvnw antlr4:antlr4 -pl :trino-grammar -nsu

# or all the grammars in the project
./mvnw antlr4:antlr4 -nsu -pl "$(find . -name \*.g4 | sed -e 's@/src/.*@@' -e 's@.*/@:@' -e 's@$@,@' | sort -u)"
kill and remove all docker containers

docker ps -a | tail -n+2 | grep . && docker ps -aq | xargs docker rm -f ; docker volume prune -f

check all commits compile

git rebase master -x './mvnw clean package -pl \!:trino-server-rpm,\!:trino-docs -T2C -DskipTests -Dmaven.javadoc.skip=true -Dmaven.source.skip=true'
sort commits for GitHub

git rebase master -x 'git commit --amend -C HEAD --date="$(date -R)" && sleep 1.05'
rebase commits within PR

This makes GitHub's diff for force-push useful.
git rebase -i master --keep-base
