Supported Eclipse versions in JMC 7.1.0.

[Marcus Hirt]

Hi Christoph,

The problem is that the dependencies from the RCP bundle will
need to look differently for supporting DS in 4.9+ vs 4.8-.

That could be solved by introducing some extra build magic 
when building 4.9, providing multiple version dependent 
manifests etc...

...but I'd like to avoid that kind of build complexity if I can.

Kind regards,
Marcus

    Hi Marcus,
    
    I understand.
    
    So why not supporting builds with all 3 of 4.8.0, 4.9.0 and 4.10.0 and using 4.10.0 as the default? Is it just because we don't want this matrix grow too big and will we have to drop stuff given the new quarterly release cadence of Eclipse?
    
    Maybe we could then also have a "lower bounds" platform 4.8.0 where we support/test an rcp configuration and then skip intermediate platforms like 4.9.0 from testing?
    
    Best regards
    Christoph
