Abstract: Managing source code change set commits to decrease time to identify software bugs in versions of a software project is provided. An initial order of relevant commits corresponding to the software project is determined in a priority queue based on a weight of each respective commit of the relevant commits. The initial order of the relevant commits is adjusted in the priority queue based on a build distance between the relevant commits of affected source files. A particular commit having a highest priority ranking is selected in the priority queue for build and test. The build and the test of the particular commit having the highest priority ranking in the priority queue is executed.
