From time to time (quite often, actually) I get: “Internal error evaluating generate-artifacts (CancellationException; see error log)” when saving my file (which triggers generate-artifacts).

Is there anything that can be done to prevent this?

Thanks for reporting. Revision 21197 (0.5.3.3) takes further measures to fix this issue. Note that this issue is a duplicate of Spoofax/227.
