Hi devs,
I'd like to propose adding the Ivy JAR to our Platform/XE distributions.
The reason is simple: it makes it possible to use the Groovy @Grab directive which makes it real easy to extend XWiki using Groovy script. Several advantages: - not having to manually hunt for transitive dependencies - not needing to stop/restart XWiki (since this is what you need to do if your groovy script needs to use some third party jars).
Here's a good usage example:
{{cache}} {{groovy}} @Grab(group='org.codehaus.groovy.modules.http-builder', module='http-builder', version='0.5.1') import groovyx.net.http.RESTClient
github = new RESTClient( 'http://github.com/api/v2/json/' )
println "|=Project|=Description|=Use Wiki?|=Use Issues?" def response = github.get( path : 'repos/show/xwiki' ) response.data.repositories.each() { repo -> println "|[[${repo.name}>>http://github.com/xwiki/${repo.name}]]|${repo.description}|${repo.has_wiki}|${repo.has_issues}" } {{/groovy}} {{/cache}}
If you try to do this without the grab directive you'll find yourself hunting down more than 30 jars which you'll need to put in your WEB-INF/lib directory, whereas here it's a single line directive. It's really powerful.
Here's my +1 to make it easy for users to use Groovy scripts.
Thanks -Vincent
