Hello guys, being a Java blogger, many Java developers ask me questions like "I am learning Java, should I also learn Maven or Gradle?" or "Is it mandatory to learn Maven to get a job as a Java developer", "Should I learn Maven or Gradle, which one is better for future?" and the less common one "Why should I learn Maven or Gradle as a Java developer?".  In the past, I have shared the best courses to learn Maven for Java developers and some useful Gradle books and courses,  as well as answered questions around Maven vs Gradle and I will try to answer these questions in this article and assert the importance of Maven and Gradle as a build tool for Java Developer.  Along the way, I will also share useful resources to learn both Maven and Gradle for Java developers.
