Apache Ant vs Apache Maven

Apache Ant is a Java library and command-line tool that runs processes described in build files as targets and tasks. Its tasks compile, assemble, test, and run Java applications, and can also build C and C++ projects. Additional built-in coverage handles archiving, file operations, execution, remote access, source control, and testing. Ant does not impose coding conventions or directory layouts on Java projects. Developers can extend it with Antlibs containing tasks and types, while optional Antlibs are distributed separately from the core release. For projects needing dependency management alongside build tooling, the project recommends Apache Ivy. Ant 1.10 requires JDK 8 or later; many tasks will not work with only a JRE. The JUnit task requires external libraries that are not bundled. Ant has been used on Linux, macOS, Windows NT descendants, Unix, and other platforms, with development focused on Linux, macOS, Windows, and Unix. Releases from version 1.6.1 onward use the Apache License, Version 2.0. The listed free plan is Apache Ant 1.10.18, distributed as ZIP, TAR.GZ, and TAR.BZ2 packages. Download guidance includes PGP signature and SHA512 verification.

Apache Maven is a free build tool for Java projects. It uses a project object model, or POM, and plugins to manage compilation, testing and documentation through a uniform build system. Maven manages dependencies, including transitive dependencies and automatic updates, and can download them from a central repository. Project metadata can produce outputs such as JARs, WARs and distributions. Maven can also generate project information, including changelogs, cross-referenced sources, dependency lists and unit test reports. Java or scripting-language plugins extend it, and it can work with source control systems such as Subversion or Git to manage tag-based releases. It runs on Windows, macOS and Linux. Maven 3.10 and later requires JDK 8 or above to execute, while toolchains can target other JDK versions. Its project layout is opinionated, so projects with unusual structures that cannot be reorganized may have to give up some Maven features or Maven itself. The software is distributed under Apache License 2.0; its listed plan costs nothing.
