Re: AW: [geclipse-dev] Eclipse 3.3 and 3.2

Hi all,

I didn't want to start my last email with my own thoughts, but of course, I 
have my opinion...

* We should not face many problems (at least problems we cannot solve) with 
the Europa Release. Therefore I would suggest to set up the build system for 
both versions, but with Callisto as reference platform. The reference 
platform should be changed with the final release of Europa.

* I expect that the only changes affect some feature definitions and their 
dependencies - in other words: I don't expect code changes.

* I personally don't like the idea of managing two development streams in our 
code repositories for our 0.5.0 release. Again, I would like to have 0.5.0 be 
built and tested against Europa, but with backward compatibility to Callisto. 

* We are using Yoxos and this is based on Eclipse 3.2 -- I hope that we will 
provide the development stream with the release of Eclipse 3.3 M7. This might 
be one solution for changing the development environment.

* For running the build and test we have to setup a 'target environment'. This 
could also be used for developing with an old 3.2 against the upcoming 
version. 

Conclusion: (1) Set up build system for Callisto/3.2, (2) Set up build system 
for Europa/3.3, (3) Switch to 3.3 as soon as both build systems are running 
properly and use 3.3 as a target for our 0.5.0 release.
