From 3ee9e2ac076733298906b92965a27a532c1cd5f5 Mon Sep 17 00:00:00 2001 From: David Pursehouse Date: Fri, 22 Jan 2016 14:30:57 +0900 Subject: [PATCH] FileRepositoryBuilderTest: Use try-with-resource for auto-closeables Use try-with-resource to create instances of FileRepository and FileWriter. "resource" and "unused" warnings no longer occur, so remove the suppression annotations.
