Rebar3 is a build tool for creating, developing and releasing Erlang libraries, applications and systems. It applies standard Erlang/OTP project conventions and provides a repeatable workflow for compiling source code, managing dependencies, running tests and producing deployable releases.
The software manages build artefacts, library paths and project dependencies automatically. Dependencies can be retrieved from source repositories, local directories or packages published through Hex, with lock files used to ensure consistent builds across different development environments.
Rebar3 is distributed as a self-contained Erlang script and can be embedded directly within a project. Its functionality can be extended through plugins, while built-in commands cover code analysis, documentation generation, test execution, code coverage, release creation and interactive development.
This is free and open source software.
