Upgrading Eclipse IDE for Java EE Developers

Question

I have been using the Eclipse IDE for Java EE Developers for Juno (4.2 SR1) that I had downloaded from the eclipse site as the custom binary. With the slowness that haunts Juno , this is almost unusable. The eclipse team is making fixes which they are advertising as being made available on their milestone builds. Can someone please guide me as to:

1. Whether one can upgrade the Eclipse IDE for Java EE Developers to pick up relevant changes from the milestones update site?
2. If yes, how are conflicts resolved?

I tried adding an update site for Juno milestones and tried an upgrade for the Eclipse platform as mentioned here
After calculating dependencies, it gave details as to why it can't proceed which I wasn't able to decipher.

Your original request has been modified.
  "Eclipse Platform" is already installed, so an update will be performed instead.
Cannot complete the install because of a conflicting dependency.

Can someone please help me out? I thought of hitting the eclipse forums as well, but thought might get a quicker response out here.

Thanks in advance!

Answer 1

From https://bugs.eclipse.org/bugs/show_bug.cgi?id=385272 ,

1. Help>Install New Software

2. use the site: junoSR1Patch

3. select Eclipse UI Juno SR1 Optimizations, install, and restart

All fixes are also in Kepler builds, however the next Kepler milestone isn't for a few more weeks yet. Your best bet is to install the official patch candidate, which works for all EPP packages as well as Eclipse "classic" SDK

Answer 2

Don't waste your time on this. Just download a new Eclipse .

Answer 3
