Oups, I forgotten to say that archetypes is the first foot a developper starts for using maven. This is why i'm concerned about archetypes. I also see archetypes a examples of using maven (for example the axistools)

My current task is now to document what i have done so far. Answers and questions inlined.

Isn't it just additional resources in the lifecycle? What i see here is just a jar around the created archetype's directory. I would also create a new packaging to provide the following functionnalities: - At install and deployment phases, an archetype needs the repository metadata to be updated (the same way as maven-plugin) > - sample properties mojo: to provide a sample configuration file > > for an > > archetype (which could be filled and used in batch mode) > > What are the current needs of a configuration file?

What i see here is a mojo which write a sample property file to be used in the generation of the project. That sample file would contains the archetype definition, and the values of the required properties of the archetype. with those properties valuated using the archetype's default values. The properties without a default values will only be set to empty (or to "please_configure_this_property") > - descriptor with attributes: refactor the current archetype > > descriptor to > > use attributes instead of xml elements > > Less is more :) By current i mean the current in the proposition.

I assume you are retaining the functionality I added where you > can incrementally add to a multiproject as well? The main problem here is an archetype of a multiproject. like the ear (ejb) archetype. And also to create suche an archetype from an existing project. The current proposition can generate a project in partial mode, and also generate a subproject in an existing project (and insert a parent element in the generated pom - and a module in the parent project). > - CRUD group mojo: mojos to change the archetype groups defined in the > > ~/.m2/archetypes.xml > > Don't really understand this, nor what archetypes.xml is for. Archetype.xml is a file which holds the list of archetype groups (just like the pluginGroups in tsettings.xml ) That mojo will only be used to change the xml file. this mojo is only for convenience and will not be really important. > - Documentation: Document the workfow of user interaction, explain > > the > > internal plexus components > > +1 :) It is what i'm doning for now. i will sent a link to the generated html file as soon as i have completed it (at least wednesday and at most in 2 weeks) > - integration tests and sibling: handle directories other than src/ > > main, > > src/test, src/site. a first case would be integration tests > > +1 :) > > > - pom.xml sibling: handle templates in the main directory. some use > > case > > would be readme files > > - translator: create a tool to translate current archetypes into > > this new > > way > > Wouldn't worry too much about this as loong as it remains backwards > compatible.
