reading the mini guide https://maven.apache.org/guides/mini/guide-creating-archetypes.html I see that it mixes the archetype = the jar that is stored to the repository and the archetype project = the Maven project that will create the archetype jar
please look at the schema in the plugin page: https://maven.apache.org/archetype/maven-archetype-plugin/ It shows the full lifecycle: - from an eventual sample project - to an archetype project - to the built archetype - an finally to the project generated from the archetype and it lists the goals of the maven-artifact-plugin to go from one step to the next one The mini guide only covers writing the archetype project by hand, and building it to get the archetype jar I hope this will help understanding the wider logic, before digging into eventual bugs or not clear messages when something gets wrong Regards, Hervé On 2023/10/05 23:15:50 Herve Boutemy wrote: > documentation probably also needs love: > you found the mini-guide, but not the plugin reference documentation that > explains much more: > https://maven.apache.org/archetype/maven-archetype-plugin/index.html > > I'm not sure mini guide was updated as it should > > Regards, > > Hervé > > On 2023/10/05 20:38:20 David Karr wrote: > > I support and maintain a platform used by a couple hundred > > SpringBoot/JAX-RS/Maven/K8S services.
