maven-gettext-plugin alow multiple sourceDirectoris

[GoogleCodeExporter]

Allow multiple source directoris may be useful.

Usage example:

1)
I'm making i18n for GWT project.
This includes multiple generated java files.  I need to pars them as well.
Also in GWT there there may be java source files that are in resources 
directory. see super-source 
http://code.google.com/webtoolkit/doc/1.6/DevGuideOrganizingProjects.html
 'Overriding one package implementation with another'

2)
Another example if I want unpacks the project java dependencies to one 
'target/source-4i18n'  and then use xgettext on all this files.
N.B. for GWT all jar files must contain java sources.

Another alternative for this usage:

3) unpacks  sources for all dependencies to one folder using 
'maven-dependency-plugin'  before calling xgettext .
  The case is I need to include sources for current project and unpacked sources.
