Publish maven artifact containing shaded sources

[zentol]

When working against the shaded dependencies it is not possible to jump to the source of a class, since we don't build source jars.

The source jars can be created by adding the following lines to the maven-shade-plugin configuration:

<createSourcesJar>true</createSourcesJar>
<shadeSourcesContent>true</shadeSourcesContent>

This is mostly blocked by legal questions:

• Do we have to modify the release process for these jars?
  • Do we have to vote on the shaded source release?
  • Do we have to modify NOTICE/LICENSE files?
• Are we allowed to publish a sources jar that isn't actually the source of the project?
• Are we allowed to publish a sources jar that not necessarily can be compiled to the binary?
  • If the shaded source and binary are the result of 2 separate shading processes we can't guarantee it.

Have we asked Apache's legal team about that?

Have you now? If there is a Jira can you link to it?

Can we add some links to link the corresponding dependencies to the source on Github ？
