Well, I downloaded and installed Eclipse Europa edition (J2EE, 3.3.x edition) and proceeded to install Adobe Flex Builder 2.0.1 plug-in/SDK edition. Turns out that the Flex Builder install does not recognize Europa. The message is seen here.
So, I guess I am downloading Eclipse classic, and hopefully the install of Flex 2.x will run smoothly.
All of this is being installed on top of Windows Vista, running the J2SDK 1.6.2.
update
I also tried Eclipse "Classic" 3.3 edition (still looks like Europa, so I am supposing, not reading all the version names, that the J2EE version and the classic version are based on the same build) and again, installation of Flex did now work.
So now, I retrieved the 3.1.2 archived version of Eclipse. Let's see how that goes.
another update
Well, it appears that Flex Builder 2.0.1 works only with Eclipse 3.1.x. That's unfortunate. Now I have three installs of Eclipse. lol.
(yet) another update
I am just responding to Ryan Stewart's (from Adobe) comment about the fact he has Flex Builder installed on Eclipse Europa! I am not surprised, as I am sure that there must be a way to get it installed. But the installer does not seem to get me any farther (I tried the installation again on Europa, and got the same result).
Final Update
I got a response again from Ryan - he mentioned that in fact, he was using Flex 3 beta on Eclipse Europa (smile). So, in fact, Flex Builder 2.0.1 does not install on Eclipse Europa (at least until someone says otherwise again). So I will install Flex 3 Beta on my Europa build of Eclipse and confirm that it works - and I will also try Ryan's suggestion of implementing multiple SDKs (i.e. Flex 2.0.x and Flex 3) into the beta - that should streamline my system a little bit!
