Summary:Methods, systems, and apparatus, including computer programs encoded on computer storage media, for how a build system uses import graphs to maintain a current compilation cache and determine when compilation targets should be recompiled. A request is received to compile a compilation target. A plurality of files are identified that are used to build the compilation target. An import graph that represents import dependencies among the files used the build the compilation target is generated for the compilation target. The import graph is traversed to assign a respective identifier to each node in the import graph. A cache key is generated from data representing import relationships represented by the import graph and data representing contents of files used to build the compilation target. If the cache key is invalid or does not exist, compiling the compilation target.
