New goal to write classpath string with all dependencies from local repo
------------------------------------------------------------------------

         Key: MDEP-26
         URL: http://jira.codehaus.org/browse/MDEP-26
     Project: Maven 2.x Dependency Plugin
        Type: New Feature

    Versions: 1.1    
    Reporter: Anagnostopoulos Kostis
    Priority: Minor


Hi to all,

'm wondering whether it would be usefull to make a new mojo that when executed 
it will output a text file containing the required classpath string to run a 
project directly from the local repository.

For instance, the file would contain a classpath string like that :

{noformat}  
    /home/foo/.m2/repository/org/java/utils/util/util-1.0.jar:/home/foo/.m2/ 
....
{noformat}  

The result file could then be used like that:

{noformat}  
    java -cp `cat resultFile` MyClass
{noformat}  

The new goal should maybe a sub-class of AbstractFromDependenciesMojo.

In that case, the "useSubDirectoryPerType" and "useSubDirectoryPerArtifact" 
params should move to (copy/unpack)-dependencies mojo classes.  Anyway, these 
params are only used by sub-classes, so, their definition should be propably 
inside of those.

Next are the parameters of the mojo i propose:

----

goal name: dependency:printClasspath

params:

|| Param Name || Type || Description
| outputFile        | File     | The file to write the classpath string into. |
| overwrite          | boolean|  If true, re-write file even when nothing has 
changed. |
| includeTypes  | String | Comma Separated list of Types to include. |
| excludeTypes | String | Comma Separated list of Types to exclude |
| includeProjectArtifact| boolean | see [this 
issue|http://jira.codehaus.org/browse/MDEP-25]. |
