Hi Jeen.

Create a new CQ with either just the delta, or with a new complete list
(whichever is easier).

This is something that we set up a few years ago after I successfully
argued that "build and test" dependencies are really the same as "works
with" dependencies. There's more in the handbook
<https://www.eclipse.org/projects/handbook/>, but no answer to Jeen's
question, so I'll fix that. The idea of grouping many "build and test"
libraries was to avoid requiring that project teams create dozens or
hundreds of CQs.

Naturally, there is some gray area here: technically, the Java compiler and
Maven are a build and test dependencies. We don't want to see CQs for the
Java compiler or standard Maven. You will notice that some of the build and
test CQs do mix in some standard Maven plugins; it's not wrong to do this,
it's just not required.

The origin of this was in things like unit tests using Mockito. The test
code itself is heavily dependent on Mockito, so it was originally
considered to be a prerequisite. I argued that the test code was "extra"
functionality and that the average consumer would just grab the JAR files
produced by the project. That is, the use of Mockito enhanced the
functionality of the project as a "works with", but was not required
(Mockito is probably a bad example since many versions of it have actually
been approved as prerequisites, but I felt that it was a good example of
what we want to enable).

You'll notice that a handful of the "build and test" CQs in IPZilla cover
technologies that are used in examples used in tests. Again, these examples
are required to run the tests, but should not be included in the
distribution.

Code generators may be a bit of a gray area. Since code generators
typically inject intellectual property we need to know about their use
(yes, I know that we can argue that compilers do this too; believe me that
I've been down this rabbit hole a few times). Create a "build and test" CQ
for code generators.

Like everything else, the EMO leans on the PMC for assistance in
determining whether or not something qualifies as a "works with" / "build
and test" dependency.

If you're not sure, ask.
