Gian Merlino commented on CALCITE-5477:
---------------------------------------
OK, I'll proceed with the plan to build with Guava 19, and am okay with the
compromise to revert that change in the next release.

> Project: Calcite
> Issue Type: Improvement

> Preconditions.checkArgument gained new overloads in Guava 20.0, which
> prevents code built using Guava 20.0 from running properly with earlier
> versions of Guava. (When building against a later version of Guava, as
> Calcite does by default, the Java compiler generates calls to methods that
> don't exist in those earlier versions.)
> Example: in Guava 20.0 there is {{checkArgument(boolean, String, int)}}; in
> earlier versions this would be handled by {{checkArgument(boolean, String,
> Object...)}}.
