**The Elasticsearch build will fail if any deprecated Gradle API is used.**

### Make a change in the build

There are a few guidelines to follow that should make your life easier to make changes to the elasticsearch build.
Please add a member of the `es-delivery` team as a reviewer if you're making non-trivial changes to the build.

#### Custom Plugin and Task implementations

    `In my youth,' said his father, `I took to the law,
      And argued each case with my wife;

 * Verify.verify(bill.status() == Status.UNPAID,

h4. Generation of plugin metadata and packaging

To create the packaging for a plugin a special Maven packaging would be created with an accompanying life-cycle in order to create the plugin metadata required and create an archive of the plugin that can be consumed at runtime.
