What is the purpose of mvnw and mvnw.cmd files?

Question

When I created a Spring Boot application I could see mvnw and mvnw.cmd files in the root of the project. What is the purpose of these two files?

Answer 1

By far the best option nowadays would be using a maven container as a builder tool. A mvn.sh script like this would be enough:

#!/bin/bash
docker run --rm -ti \
 -v $(pwd):/opt/app \
 -w /opt/app \
 -e TERM=xterm \
 -v $HOME/.m2:/root/.m2 \
 maven mvn "$@"
