NRE from GenerateDepsFile during Roslyn build

tmat commented 5 years ago

This is a non-standard build with my local changes. Not sure how to repro this exactly.

@nguerrera is this in the cache code?

@tmat what version of the .net core SDK does this happen?

nguerrera commented 5 years ago

Not assets cache code of that's what you're asking.

nguerrera commented 5 years ago

What does non standard with local changes mean?

tmat commented 5 years ago

@nguerrera I was changing some of the build scripts to port to Arcade and this was built with incorrect combination of switches. If the issue is not obvious from the above info I can try to recreate the repro.

nguerrera commented 5 years ago

I'll check the binlog and source at that stack and let you know if that's enough.

nguerrera commented 5 years ago

Sorry for letting this sit. The binlog doesn't give a hint. Closing until we see another instance with repro.
