## [Java] Annotation Type Grapes

- groovy.lang.Grapes

-     public @interface Grapes

  Sometimes we will need more than one grab per class, but we can only add one annotation type per annotatable node. This class allows for multiple grabs to be added.

  For example:

       @Grapes([@Grab(module='m1'), @Grab(module='m2')])
       class AnnotatedClass { ... }

  You can override an implicit transitive dependency by providing an explicit one. E.g. htmlunit 2.6 normally uses xerces 2.9.1 but you can get 2.9.0 as follows:

       @Grapes([
           @Grab('net.sourceforge.htmlunit:htmlunit:2.6'),
           @Grab('xerces#xercesImpl;2.9.0')
       ])

  Obviously, only do this if you understand the consequences.

  You can also remove transitive dependencies altogether (provided you know you don't need them) using `@GrabExclude`. For example, here is how we would not grab the `logkit` and `avalon-framework` transitive dependencies for Apache POI:

       @Grapes([
         @Grab("org.apache.poi#poi;3.5-beta6"),
         @GrabExclude("logkit:logkit"),
         @GrabExclude("avalon-framework#avalon-framework")
       ])
       import org.apache.poi.hssf.util.CellReference
       assert new CellReference(0, 0, false, false).formatAsString() == 'A1'
       assert new CellReference(1, 3).formatAsString() == '$D$2'

  It is also sometimes also useful to use `@GrabConfig` to further adjust how dependencies are grabbed. See `@GrabConfig` for further information.

    Required Element Summary
    Type | Name and Description
    --- | ---
    `Grab[]` | `value`

    Optional Element Summary
    Type | Name and Description
    --- | ---
    `boolean` | `initClass` This will be pushed into the child grab annotations if the value is not set in the child annotation already.

  - ### Inherited Methods Summary

    Inherited Methods
    Methods inherited from class | Name
    --- | ---
    `class Object` | `wait, wait, wait, equals, toString, hashCode, getClass, notify, notifyAll`

- - ### Element Detail

    - #### public boolean initClass

      This will be pushed into the child grab annotations if the value is not set in the child annotation already.

      This results in an effective change in the default value, which each @Grab can still override

      Default:
        true
