Build tools are essential applications used in software development to automate the process of turning source code into executable programs. They streamline various tasks, including compiling code, managing dependencies, running automated tests, and packaging applications for deployment. This automation is crucial for improving efficiency and ensuring consistency in the development process.

There are several popular build tools, especially in the Java ecosystem. For instance, Apache Maven and Gradle are two widely used tools. Maven is an XML-based project management tool that simplifies project setup and dependency management, while Gradle offers a more flexible and powerful build automation system using a Groovy-based DSL. The choice between these tools often depends on the specific needs of the project and the preferences of the development team ²³.

In addition to Java, build tools are also available for other programming languages, each tailored to the unique requirements of those languages and their ecosystems ⁴.
