One of the essential features that enhances developer productivity is the Maven auto import functionality. This article will guide you through the process of enabling Maven auto import in IntelliJ IDEA.

Introduction to Maven Auto Import

Maven auto import is a feature that allows IntelliJ to automatically download and import dependencies from your project's pom.xml file. This feature is particularly useful in large-scale projects where dependency management and updates are frequent.
