RFS: gradle/1.5-1

[Emmanuel Bourg <ebourg@apache.org>]

Hi all,

I upgraded gradle to the version 1.5 and I'm looking for a sponsor to
upload it. This update also fixes a compilation issue with Java 8. I was
able to rebuild gradle itself and multiverse-core with this new version.

Here is the changelog:

  * New upstream release
    - Added a build dependency on libjatl-java
    - Refreshed the patches
  * Fixed a compilation error with Java 8
  * Standards-Version updated to 3.9.5 (no changes)
  * Updated the version of Guava used to fix a clean error
  * Use XZ compression for the upstream tarball
  * Switch to debhelper level 9

Thank you,
