cd yourmavenproject
mvn -N io.takari:maven:wrapper
You can set a specific Maven release (but not SNAPSHOT) by adding a maven parameter :
cd yourmavenproject
mvn -N io.takari:maven:wrapper -Dmaven=3.3.3
Alternatively, you can set a specific download url (which could point to a SNAPSHOT version of Maven) by using the distributionUrl parameter :
cd yourmavenproject
mvn -N io.takari:maven:wrapper -DdistributionUrl=http://server/path/to/maven/distro.zip
This will create a mvnw and a mvnw.bat file as well as a .mvn folder in your project. You can now use mvnw instead of mvn in all project builds, which will download the configured Maven installation as required.
