Subject Re: MySQL FOSS License Exception
Date Fri, 30 Sep 2016 11:18:36 GMT
As Shane points out, such "Special exceptions" would in theory be good
enough for an open source project, but it restricts commercial
downstream users beyond the ASF license (which gives them the
"freedom" to NOT distribute the source)

https://www.apache.org/legal/resolved#category-x


However you can have an optional dependency and give users
instructions on how to build/add mysql support - given that the
project generally does not require it (most users would not need it).
With JDBC and Maven's <optional>true</optional> (can SBT do that?)
this should be quite easy to achieve for the mysql client lib; several
ASF projects already do this:

https://github.com/search?q=org%3Aapache+mysql&type=Code


What would NOT be ok is an "Apache mySQL Friend" - e.g. an ASF product
that would be pointless without the (L)GPL component - even if you
managed to sneak away from a compile-dependency. :-)

(Where this gets tricky is if a project has such optional Connector
plugins, but the plugin is released on its own)
