Abstract: Dependence-based software builds are described. In embodiments, authored source code is received as inputs to a computer device to develop a buildable unit of a software build project. The software build project includes multiple buildable units that can be allocated for independent development among multiple developers, such as at computer devices local to each developer. At the computer device, dependent buildable units are identified that have a dependency relationship with the buildable unit for execution. The authored source code of the buildable unit is then validated to determine that the buildable unit executes with the dependent buildable units for error-free execution before the buildable unit is subsequently provided to a software build service that compiles the multiple buildable units to generate the software build project.
