private ImmutableMap<BuildTarget, HashCode> buildTargetGraphAndGetHashCodes(Parser parser, BuildTarget... buildTargets) throws Exception {
    // Build the target graph so we can access the hash code cache.
    ImmutableList<BuildTarget> buildTargetsList = ImmutableList.copyOf(buildTargets);
    TargetGraph targetGraph = parser.buildTargetGraph(eventBus, cell, false, executorService, buildTargetsList);
    ImmutableMap.Builder<BuildTarget, HashCode> toReturn = ImmutableMap.builder();
