Methods, systems, and computer program products are included for integrating software components. Source code corresponding to the software components is parsed to identify method calls. Method contracts, which contain identifying information corresponding to the method calls, are determined. The method contracts are used to query a dependency data store to identify dependencies that correspond to the method calls. Dependencies that are determined for a component are compared with dependencies for another component in order to identify dependencies that may be used to build the components together, and also to identify conflicting dependencies.
