What is the main role and purpose of a build tool in the software development process?

A build tool automates the process of compiling, linking, and preparing a software product for launch or distribution. Its main role is to simplify and standardize the project build process, minimize manual errors, and ensure repeatability.

Main tasks of a build tool:

• Compiling source code into executable files or libraries
• Managing dependencies and their loading
• Running tests
• Creating packages and artifacts for deployment
• Automating routine tasks (code generation, style checks, etc.)

Examples of popular tools: Maven, Gradle, Make, Ant.

Thus, a build tool helps developers focus on writing code rather than manually managing the build process.
