From 0467f8139e405a5d24a7aac9104ad3f7effbf6e1 Mon Sep 17 00:00:00 2001 From: trojanbug Date: Fri, 6 Jan 2017 17:10:35 +0100 Subject: [PATCH] Changed build mojo to enable providing explictly set name in resources (renaming) - if the resource selection names a single file. That way it is possible to use the build output where the name is of significance in the container - e.g. WAR name copied to Tomcat webapps directory defines the context path of the deployed app. --- .../java/com/spotify/docker/BuildMojo.java | 34 +++++++++-- .../com/spotify/docker/BuildMojoTest.java | 57 ++++++++++--------- 2 files changed, 57 insertions(+), 34 deletions(-) diff --git a/src/main/java/com/spotify/docker/BuildMojo.java b/src/main/java/com/spotify/docker/BuildMojo.java index df91822c..8360bf81 100644 --- a/src/main/java/com/spotify/docker/BuildMojo.java +++ b/src/main/java/com/spotify/docker/BuildMojo.java @@ -49,6 +49,7 @@ import org.codehaus.plexus.component.configurator.expression.ExpressionEvaluationException;
