Unfortunately, we don't support analyzers today. This is being tracked by #43.

Oh, sorry for creating duplicated issue.
I hope it would be supported.

[DustinCampbell]

It's not a problem at all! We do hope to get to this eventually. Note that analyzers should still run and return errors during build.
