Allow distribution of artifact types other than jar (better solution then as 
indicated at http://jira.codehaus.org/browse/MPDIST-13?).
--------------------------------------------------------------------------------------------------------------------------------------

         Key: MPDIST-26
         URL: http://jira.codehaus.org/browse/MPDIST-26
     Project: maven-dist-plugin
        Type: Improvement
 Environment: Not of importance.
 Reporter: Davy Toch
 Attachments: multiprojectProperties.txt, postGoal.xml

The goal dist:build-bin should also allow to include artifacts different then 
the ones created by jar:jar (e.g. wars, ears, ...). A solution was already 
proposed at http://jira.codehaus.org/browse/MPDIST-13.

Currently, we're writing a postGoal for dist:prepare-bin-filesystem that:
1. determines the current project 'type' (ejb, war, jar, ...)
2. removes the already generated jar if the current project type is different 
from 'jar'
3. attain the goal 'type':'type' to (re)create the artifact
4. copy the artifact to the binary distribution directory

Cf postGoal.xml included as attachment.

This postGoal currently uses the property maven.multiproject.type from the 
multiproject plugin:
1. maven.multiproject.type = 'master' :
- master Maven project from which other projects can inherit (to avoid POM 
configuration duplication)
- steps 1 and 2 of our custom postGoal are executed
2. maven.multiproject.type <> 'master' :
- Maven projects that create artifacts (jars, ears, ...)
- type = 'jar' : step 1 executed
- type <> 'jar' : steps 1 to 4 executed

Cf multiprojectProperties.txt included as attachment.

Having a solution similar to the postGoal but already integrated in the plugin 
would allow minimizing custom scripting in maven.xml and have a more generic 
dist plugin. Also remark that an alternative to using maven.multiproject.type 
can be chosen (e.g. maven.dist.artifact.type), in order to avoid being 
dependent on properties of the multiproject plugin. 

The only problem I can see is that the prereqs='jar:jar' in the dist plugin 
would somehow have to be replaced by a call <attainGoal 
name="${type}:${type}"/>, meaning that it is possible that the goal 
${type}:${type} will be called more than once.
