maven can't find archetype in my repository

Question

I'm trying to create my own maven archetype. For now, I'm going through this tutorial [here][1] without success. I'm able to build the archetype project okay, but when I try to generate a project from that archetype I get the error below. Maven can't seem to find the archetype I created. Can any one spot my problem? Is there some other recomended tutorial for createing a maven archetype? Thanks.

Maven version 3.0.3

Build Error:

Answer 1

For using a customized archetype, there has to be an entry made in the archetype-catalog.xml file which resides in the .m2/repository/archetype-catalog.xml in your home directory. For doing so, you need to install the archetype by using the following command:

mvn install archetype:update-local-catalog

After that, you will be able to use your new archetype while creating a new Maven project with the mvn archetype:generate command.

Answer 2

I needed to include -DarchetypeVersion={my.archetype.version} in the mvn archetpe:generate command
