Maven 4 Is Finally Here: Everything You Need to Know About the Biggest Update in 15 Years
After 15 years of waiting, Maven 4 brings a modernized POM model, separated build and consumer artifacts, tree-based lifecycles, and a migration tool that actually works. Here's what Java developers need to know.

Works with Maven 3.9 and Maven 4.
