1. A method comprising: while executing a computer application program, loading, by a processing device, a class file associated with the computer application program, wherein the class file depends on an import class file to run; examining classpath information associated with the computer application program; determining that the import class file is not found at a first location specified by the classpath information, the first location comprising at least one of a local directory or a network accessible location on a remote system; reading repository information to determine an alternate location for the import class file, wherein the alternate location for the import class file is different from the first location for the import class file, wherein the repository information comprises alternative classpath information that is stored separately and received independently from the classpath information; locating the import class file at the alternate location; and updating, by the processing device, the classpath information with the alternate location of the import class file by writing the alternate location over the first location in the classpath information.
