/**
 * 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: *

*

 * {@code @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: *

 * {@code @Grapes}([
 *     {@code @Grab}('net.sourceforge.htmlunit:htmlunit:2.6'),
 *     {@code @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 {@code @GrabExclude}. * For example, here is how we would not grab the {@code logkit} and * {@code avalon-framework} transitive dependencies for Apache POI: *

 * {@code @Grapes}([
 *   {@code @Grab}("org.apache.poi#poi;3.5-beta6"),
 *   {@code @GrabExclude}("logkit:logkit"),
 *   {@code @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 {@code @GrabConfig} to further adjust how dependencies * are grabbed. See {@code @GrabConfig} for further information. */ public @interface Grapes { Grab[] value(); /** * 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 */ boolean initClass() default true; }
