Hi,

I have 2 problems and I would like some help or advise on these matters.

1. – Is there is a way by which i can have 2 separate versions of myeclipse on my system. I have 2 separate eclipse versions in separate directories. e.g.- c:dev/sun/eclipse has eclipse 2.1.3 and c:dev/moon/eclipse has 3.0M9 . For both these versions I have separate myeclipse installers. Plus I want to use jdk 1.3.1 with eclipse 2.1.3 and jdk 1.4.2 with 3.0M9. How should I do this? Please guide.

2. – What is the difference between 2.1.X versions and 3.0Mx versions

Thanks,

Mukund

mukund,
You can definately have multiple versions of Eclipse and MyEclipse, many people like to do this to have Eclipse 2.1.x for stable development and Eclipse 3.0 M-builds for testing.

A very popular directory structure for this type of thing is something like this:

C:\eclipse\2.1.3
C:\eclipse\3.0m8

You’ll note that when you unzip the SDK Zip files from Eclipse, it creates a directory called “eclipse”, typically you rename this directory to the version, and drop it in your C:\eclipse dir, which will give you the above organization.

You will want to do something almost identical with MyEclipse:

C:\myeclipse\2.7.1
C:\myeclipse\3.7.2

And then when you run the MyEclipse installers, and they ask for your respective version of Eclipse, you point them to the appropriate install (e.g. C:\eclipse\2.1.3) and then when the installer asks for a location, point it at the dir you made (or let the installer make it) (e.g. C:\myeclipse\2.7.1)

2. – What is the difference between 2.1.X versions and 3.0Mx versions

There is no better way to answer that then to have you read/view every single “New and Noteworthy” set of pages for every M-build release of Eclipse 3.

This is a link to the M9 build notes, at the bottom are links to ALL previous M-build notes. You can look at all of them for screenshots and quick blurbs about the new features.
http://download2.eclipse.org/downloads/drops/S-3.0M9-200405211200/eclipse-news-M9.html

If you don’t want to read all of it, then my summary would be something like: The difference, technically and usability-wise, between Eclipse 2.1 and Eclipse 3.0 is probably the same gap of difference between Windows 98 and Windows XP. Its a pretty huge difference. Eclipse 3.0 seems to be oozing cool enhancements, functionalities and producitivty enhancements. It will be a very slick release.
