I'm using Eclipse Juno 4.2, downloaded from here.
On previous installs, I've been using 3.7, and I've been using WindowBuilder, which I find very useful. I noticed it wasn't included this time, so I used this update site provided on this page (the zip file download gives a "file unavailable" error).
However, when I run the install, it rapidly climbs to 28%, then freezes. After half an hour, I get a very long error, whose message starts with this text:
An error occurred while collecting items to be installed session
context was:(profile=epp.package.java, phase=org.eclipse.equinox.internal.p2.engine.phases.Collect, operand=, action=).
Multiple problems occurred while downloading. Unable to read repository at http://download.eclipse.org/windowbuilder/WB/integration/4.2/plugins/org.eclipse.wb.core_1.5.0.r42x201205291332.jar.pack.gz.
Does anyone know how I can go about installing it?
Try the juno repository at http://download.eclipse.org/releases/juno/.
