Maven: Taming the Beast

Roberto Cortez

Love it or hate it (and a lot of people seem to hate it), Maven is a widely used tool in Java development. We can consider that Maven has been the de-facto standard build tool for Java over the last 15 years. Most experienced developers already have their share of Maven headaches. Unfortunately, new developers are going through the same hard learning process, because they don’t know how to deal with Maven particularities. “Why is this jar in my build?”, “I can’t see my changes!”, “The jar is not included in the distribution!”, “The artifact was not found!” are common problems.

In this session, we will start with the basics and learn about the principles and foundations in which Maven is built on. From there, we will dig deep and learn how to improve, enhance and debug your build. In the end, this will provide you a good understanding on how to use Maven to build any kind of Java project.

What you'll learn-and how you can apply it

By the end of this live, hands-on, online course, you’ll understand:

  • How to configure Maven
  • How the Maven Build Lifecycle works
  • How Maven deals with Dependency Management

And you’ll be able to:

  • Add Maven plugins to enhance your build
  • Understand build errors and how to fix them
