Subject Re: [DISCUSS] - Camel Maven Archetypes - Generating files with ASF license headers
Date Wed, 04 Jul 2012 09:44:09 GMT
Very good idea. I have done some research:

So it looks like we are required to have the license in all files we 
have in svn and also in each artifact we distribute. The only exemption 
are very simple files with no creativity.

Still an archetype could strip that header when generating the effective 
code. The problem is that we are then unsure what this means for the 
user. If the resulting file contains
enough creativity then it may be copyrighted and may not be used without 
a license (at least that is what I understood).

There seems to be no issue with a decision about generated code or 
archetypes in the jira. So I have created an issue to get that resolved:
