US Patent 10255065 Automatically building software projects

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for performing automatic builds of snapshots using software packages with highly similar contents. One of the methods includes computing, by a source code analysis system, a respective similarity score between contents of a particular snapshot and contents of each software package of a plurality of software packages in one or more package repositories. A highest-scoring software package for the snapshot is determined using the computed similarity scores. An automatic build of the snapshot using the highest-scoring software package is performed, including identifying one or more dependencies and one or more build commands from the highest-scoring software package, installing the one or more dependencies in a build environment of the snapshot, and executing the one or more build commands in the build environment of the snapshot.
