Hi,
I'm very satisfied of Eclipse 3.0.2 for my Java programming until now,
but I would like to be able to use the 1.5 syntax. I understand that I
need to download the 3.1 Milestone version for that. The problem is: I
also use the Omondo UML-plugin, which explicitly states it needs the 3.0
branch. So the question is: Can I install 3.1 without removing 3.0.2,
and use them both at the same time? I would then use 3.1 for editing my
files, and 3.0.2 for building a nice UML-scheme out of it.
Anybody have any experience with this?
Basically:
- can 3.1 and 3.0.2 exist together on one machine?
- if yes, can they share the same workspace?
- does Omondo Umlplugin work with 3.1?
Cheers, H.

Yes, just put them in tow separate directories.

Yes, but...

....but sharing workspace may take you into problems....
1st a workspace cannot be used at the same time by two running instances of
Eclipse.
Then, under a workspace, you have a set of cached informations, like
preferences.
Formats may have change between the 3.02 and 3.1 version.
And at the minimum if they have not changed, the internal format for indices
have hanged, so it would trigger a rebuild each time you are attaching a
workspace to a different version of Eclipse.
In practice, you are using some team repository like CVS, I would ratherr
set-up two wokspaces: one for each version of Eclipse, and share the info
between the wo via the team repo.
Just to be on the safe side, and avoid weird unsupported things.
I am pretty sure that worksapce are not backward compatible, but I may be
wrong.
I know I have been using 3.0.X workspaces with latest 3.1 milestones back
and forth, but I would not recommend to try this at home :-)

That is a question for Vladimir!
Not AFAIK per their web site.
But I would give it a spin... Now it may not work not because of Omondo
itself but also because of other components like GEF, EMF, and UML2 Omondo
depends on.
And encourage Omondo to release soon a 3.1 version, which they will surely
do once 3.1 is final in a few weeks!
Now the other question is: does Omondo support Java 5?
Once again a question for them!

I'm working on this all alone, so didn't use CVS till now, can you give
me some hints on how to do this? I'm on WinXP SP2.

I would if this weren't a project which has to be finished by monday
morning, and which counts as an exam of programming...

Ah, I think you hit the weak spot there...
Thanks, H.
