I wonder if my mail was sent on the mailing list so I send it again, sorry if
you already receive this mail.
Hi all,
I'd like to make my own artifact/archetype and I'm facing an issue when trying
to install it, precisely when it tries to make the jar file.
Here is the output :
C:\HOMEWARE\Maxime\myartifact >mvn install

The "myartifact" folder contains a pom :

Another pom in myartifact\archetype-resources and a archetype.xml in
myartifact\META-INF\maven.
I followed http://maven.apache.org/guides/mini/guide-creating-archetypes.html .
Does anyone know where it could come from ? Let me know if you need some other
information to help me.
Thanks in advance,
Regards,
Maxime
