Apache Ant
Apache Ant is a Java-based build tool and library developed by the Apache Software Foundation, used to automate software build processes. It uses XML-based build files to define targets and tasks for compiling, testing, packaging, and deploying Java applications. Ant provides a Java API for programmatic build execution, custom task (Antlib) development, and build file manipulation. The companion Apache Ivy project provides dependency management and artifact resolution for Ant-based builds.

Features
Define build processes using XML-based build files (build.xml) with targets, properties, and tasks.
Over 150 built-in tasks for file operations, compilation, testing, archiving, and network operations.
Extend Ant with custom task libraries (Antlibs) written in Java for project-specific automation.
Programmatic Java API for embedding Ant build execution within applications and test frameworks.
Runs on any Java-supported platform including Windows, macOS, and Linux.
First-class dependency management via Apache Ivy for resolving Maven and Ivy repositories.
Integrates with Jenkins, TeamCity, Bamboo, and other CI systems via command-line invocation.
Supports Java 8 and higher (Ant 1.10.x), with broad backward compatibility for legacy build files.
Use Cases
Compile, test, package, and deploy Java applications using declarative XML build scripts.
Maintain and modernize legacy Java build systems that predate Maven and Gradle.
Orchestrate complex multi-step build processes with conditional logic and property-driven configuration.
Run Ant targets as build steps in Jenkins, TeamCity, or other CI/CD systems.
Resolve and cache project dependencies from Maven Central and custom repositories using Apache Ivy.
Automate C/C++ or other non-Java project builds using Ant's exec and cc tasks.
Integrations
