Building from source

Building

Requirements:

A Linux class machine (can be a VM).
- Some of the build scripts rely in bash/sed/grep and related tools, so it will not build on a Windows machine. I’m unsure if it will build on a Mac.
The normal build tools for a Java project
- JDK 8, 11, 17, 21 and 23 all need to be installed and defined in the ~/.m2/toolchains.xml
  - All of these are needed to ensure the code works in all UDFs. Some of them only run on Java 8 (like Hive), some (like Flink) only work on Java 11 and some UDFs (like ElasticSearch and Trino) only work on Java 17.

The ./start-docker.sh script launches a docker based build environment with all needed tools and configs.

and then simply do:

mvn clean package

Toolchains

This is the content of my ~/.m2/toolchains.xml on my Ununtu 22.04 LTS machine.
