[tycho-user] Building an RCP product against different Eclipse versions

[Andreas Pakulat <andreas@xxxxxxxxxxxxx>]

Hi,

this might not be exactly a tycho question, but since my main problem is 
related to knowing which platform tycho builds at a given time I'm hoping the 
bundled knowledge here can help me out.

I'm facing the challenge that I have to package our RCP product with two 
different versions of Eclipse - depending on the platform. In particular I 
want to bundle Eclipse 4.12 for macOS and against 4.7 for all other 
platforms.

My current solution is manual, one has to specify a profile name on the 
commandline for the macOS build. That profile sets up a different path for 
the 'eclipse-mirror' repository and then building our product happens with 
Eclipse 4.12 instead of 4.7. I'm then doing two builds of the product, once 
without profile specified and once with the macOS profile.

I'd prefer some 'automatic' way of doing this, but my maven/tycho/Eclipse foo 
is too weak to figure out a better idea how to do this. In particular since 
we also build the product locally sometimes and it's easy to forget about the 
separate profile.

I suppose one way would be for the profile to automatically activate when 
maven generates the product for macOS, but I wouldn't know what variable or 
so to check for this. Maybe I'm also overlooking other options that would 
achieve the same result?

Andreas

PS: I'm aware both versions of Eclipse may be considered old, but for reasons 
beyond my control that's what I have to stick with for now.
