Build automation is an important aspect of software development. This refers to the process of automating tasks required to convert source code into executable programs. In this article, we will compare the two most popular build tools for Java development: Maven and Gradle. Maven uses a declarative style and XML syntax. Gradle is a modern build system that also uses a declarative approach, but the developer can easily extend building logic because build scripts are written in Groovy DSL or Kotlin DSL.
