A client/server application is provided for performing synchronous builds on a server. The client, running on a development platform, communicates with the server and, together, they complete a build transaction. In a build transaction, the client transfers all the resources that are needed for the build to the server. The server completes the build and returns any resulting output resources to the client. The end user invokes the client for each build transaction and such calls may be embedded in a script facilitating automation of the overall build process.
