You should have JDK17 and Maven 3.9.0 or above.
From the root directory:
mvn clean package
Say you're wanting to contribute a modification to module of Jooby via a regular pull request. After clone/checkout of this repo, you can target just one module with command-line arguments for Maven like so:
# example module is 'jooby-hikari' - replace as appropriate
mvn package -pl jooby-hikari -am
Note: Maven builds the smallest amount on dependent modules necessary before it gets to this one. The resulting build time is shorter, and less is downloaded from Maven Central to your local cache of jars.
