From 11eef80c891b8b756684600e39add76cede30996 Mon Sep 17 00:00:00 2001 From: Nik Everett Date: Mon, 29 May 2017 16:08:39 -0400 Subject: [PATCH 1/3] Test that gradle and Java version type match Both gradle and java code attempt to infer the type of a each Version constant in Version.java. It is super important that they infer that each constant has the same type. If they disagree we might accidentally not be testing backwards compatibility for some version. This adds a test to make sure that they agree, modulo known and accepted differences (mostly around alphas). It also changes the minimum wire compatible version from the released 5.4.0 to the unreleased 5.5.0 as that lines up with the gradle logic.
