I've just checked and ivy dep is in the groovy-all pom.xml file but as an optional

ahah… that's funny and ironic. It used to be there but thanks to Thomas Mortagne
it's no longer! :)

Yes, it should. I'm interested in Guillaume's motivation as well. On 08/22/2011 04:43 AM, Vincent Massol wrote:
With this reasoning we should remove groovy too (the macro) since the majority of users
don't need it. IMO they go together and we should leave them together.
So for me either we consider that for now we bundle the groovy macro and we add the ivy
dep or we remove the groovy macro by default.
Said differently I'd like to add the ivy dependency in the groovy macro's
pom.xml.
Another way of viewing this is that groovy-all.jar should have a dep on ivy by default (I
don't know why it doesn't and it may well add it in the future - I'll ask
Guillaume). 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:
-0.
It is a very cool feature, but I don't think it's something useful for a
majority of users. It's something very useful in a development wiki like
we have on xwiki.org, but it adds almost 1M extra size, and increases
the classpath and the permgen requirements.
I think the extension manager would make it easy to install Ivy when needed. Thanks

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.
