An association between two or more segments of committed program code can be determined so that the segments of committed program code can be used together for building a software project. For example, one or more communications can be received and indicate that two or more segments of program code are to be committed to one or more repositories associated with a software project. Thereafter, the segments of program code, a database, or other information can be analyzed to determine an association between the two or more segments of program code. Based on the association between the two or more segments of program code, the two or more segments of program code can be integrated together into combined program code. A build tool can then build the software project using the combined program code.
