One of the key benefits of using Maven is its
effective dependency management mechanism.
As the project complexity grows, the number of Jar files and other external APIs that might be needed for the project to consume/interact might grow. This might lead to difficulties in managing such dependencies along with appropriate versions.
With Maven, all dependencies of your project are maintained in a
single pom.xml file. Maven takes care of downloading these dependencies into the local repositories and makes them available for the project.
