Subject: [PATCH] This is a quick fix to attempt to resolve most of the travis
 failures Most of the failures have been due to transient network failures,
 that are causing dependency artifact downloads to fail Maven does not have a
 way to retry this without restarting the whole build, so the mvn dependency
 plugin is the best bet Unfortunately, running a dependency:resolve on the
 project returns yet to be compiled dependencies, and causes it to fail...
 There is an option to excludeGroupIds and excludeArtifactIds in the docs for
 this goal, but unfortunately they don't seem to work This drafts a dummy pom
 in a quick and dirty way, just to download all the deps in one go, while
 retrying for RETRY_COUNT times if it fails
