upgrading to Nightly builds of Eclipse

I am using the stable version of Indigo - for JavaEE - and I was wondering if I开发者_Go百科 want to upgrade to a nightly build of Indigo is there kind of "update sites" that I enter and upgrade it or I have to download the whole new package of an Indigo nightly builds, then I have to install my all other development plugins which well takes time...so is there any kind of "update site" for nightly builds as well?

The list of p2 updates site is here:

Nightly builds toward 3.8
http://download.eclipse.org/eclipse/updates/3.8-N-builds

But that is for 3.8, not Indigo 3.7.
And regarding their natre, they might not be the best choice.

Nightly Builds

Nightly builds are produced every night from whatever has been released into the HEAD stream of the CVS repository.
They are completely untested and will almost always have major problems. Many will not work at all.
These drops are normally only useful to developers actually working on the Eclipse Project.
Because nightly builds are produced in a different way from integration builds, bundles from nightly builds should not be mixed with bundles from other types of builds

A fresh installation is usually safer than trying to modify an existing (and running properly) Eclipse.
For the plugins issue, see "How to copy plugins between two eclipses".

You should check out a continuous integration tool like http://jenkins-ci.org/ or http://hudson-ci.org/, those are more suited to do scheduled builds than eclipse.
