MDLSITE-4323 I made it possible to detect shifter lint issues:
A note about the current implementation:
I could be clever about getting the full shifter verbose output and parsing to work exact lines affected by a failing lint check. That would mean we could apply diff'ing solution and avoid reporting unrelated errors to a patch. But I am not, because:
a) I think it would be fragile
b) I think it is reasonable that we make sure shifter never reports errors when built. The ugly 'err' reported in output should be exceptional.
Unfortunately this is blocked by
MDL-45364 so wasn't merged. We should also do it on the post checker.
