Arnaud Heritier updated MAVEN-1656:
-----------------------------------
Fix Version: (was: 1.1-beta-3)
> Doco that explains the protocols required to allow maven.xml or any
> plugin.jelly to inject values into or retrieve values from another plugin
> ---------------------------------------------------------------------------------------------------------------------------------------------
>
> Key: MAVEN-1656
> URL: http://jira.codehaus.org/browse/MAVEN-1656
> Project: Maven
> Type: Bug
> Components: documentation
> Versions: 1.1-beta-1
> Environment: All
> Reporter: Andy Glick

> Brett recently posted a suggestion to someone who asked how to access the
> contents of "plugin a" from the context of "plugin b" or from maven.xml.
> Brett stated that "plugin a" would have to be initialized before it could be
> accessed, and that from what I could understand he recommended 1 or 2 ways to
> do that:
> 1) reference the artifact plugin's namespace in the project tag
> 2) specify <j:set target="plugin-name" scope="parent" var="some.plugin.var"
> value="some.value"/> (I think that this is the proper syntax, but I'm not
> sure :-).
> Thierry Lach, who asked the question this time around, reported that using
> the artifact namespace didn't work in his instance, but that setting the
> scope to parent did. I'm hoping that we can put together a fairly
> comprehensive explanation about what is going on here, and if that means
> explaining why the project gave up on Jelly and switched to M2, then so be it.
> See http://news.gmane.org/gmane.comp.jakarta.turbine.maven.user for the
> postings
> Given that during the last couple of months Vincent Massol recommended that
> people use the now deprecated <dependency-handle> mechanism on the
> mavenbook.org site (see Tip #2), I should think that there ought to be a
> priority on documenting this issue in an obvious place, probably the FAQ, but
> also on the Maven Jelly tags get and set entries.
> If this is actually explicitly documented somewhere, I'm sorry to have wasted
> anyone's time. I have seen several plugins that have successfully used the
> artifact namespace tag, so there must be some way that people have learned
> this. I simply wish that I knew how they had done so. ;-)
> I'm willing to write the doco if someone would explain the details.
