Re: [mdt-papyrus.dev] Guava dependencies
Hi Camille

I'm not an expert on Guava; just a victim of much pain when Xtext and Acceleo had different opinions about what I wanted, and again when OSGI moved to Java 6.

The comments from itemis were that problems were with experimental and clearly marked API, rather than deprecated API. itemis report that they have eliminated all their experimental usage.

Being unambitious with Guava would seem to be a necessary practice for sound portable code.

Since you use Xtext, you have a tight coupling to whatever itemis choose to do; best to be flexible.

Hi Ed,



Well, I don’t really have any better solution. Guava APIs move really fast, which makes it difficult to actually fix the issues (And the sources don’t seem to be included in Orbit). I don’t really feel like exploring new Guava APIs every 6 months to find the replacement for each deprecated method.

 

Soft dependencies are not a solution either, because it will just not work on Guava >= 11.0.x (The method doesn’t exist anymore).

 

As we don’t reexport the Guava dependency, and probably don’t expose it too much to the outside, I have the feeling that explicit/restricted dependencies is the best (only?) way to go.

Hi Camille

Explicit bounds creates significant hazards that users who install Papyrus and something else will have an exciting time.

I hope the use of explicit bounds in Papyrus will be prohibited from at least M6 inwards.

NB Guava 12 is Java 6  and Luna is unuseable on Java 5 so installing Guava 11 may not be practical with DI and other clever facilities.

Use an explicit dependency to Guava [10.0.0, 11.0.0) (i.e. excluding Guava >= 11.0.0)
