Doco that explains the protocols required to allow maven.xml of any
plugin.jelly to inject orm 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.
