Rebar3 is an Erlang tool that makes it easy to create, develop, and release Erlang libraries, applications, and systems in a repeatable manner. Rebar3 will: respect and enforce standard Erlang/OTP conventions for project structure so they are easily reusable by the community; manage source dependencies and Erlang packages while ensuring repeatable builds; handle build artifacts, paths, and libraries such that standard development tools can be used without a headache; adapt to projects of all sizes on almost any platform; treat documentation as a feature, and errors or lack of documentation as a bug. https://github.com/erlang/rebar3/issues/ erlang/rebar3
