Name issue for package and appName properties

[bsaby]

The expression '[A-Za-z0-9_-.]+' is good to name groupid and artifactid.
And the value of package property will set the default value to groupid, and value of appName will use the artifactid to set the default name prefix. Now the issue is that the expression '[A-Za-z0-9_-.]+' do not apply to package and appname if user choose default value of package and appname.

e.g.

[mjg123]

I just popped up to report this too. I think this might be a maven problem - it seems that maven-archetype-simple also generates code that doesn't compile if you put a - in the package name, but if there is a way for the Azure function archtype to paper over that it would help developers, IMHO.
