Eclipse Update Site is unavailable

Petr,

We have had the current version available for a week, and we received no
reports of similar problems; I have just tried and all works here.

From your logs, it seems that Eclipse is trying to download 2.7.3.RC2, but
the files were replaced by 2.7.3.final, and Eclipse should see the new ones
instead. You may try to refresh your update site list in Eclipse, leaving
only the scala-eclipse-plugin site and removing the nightly one. Also, if
you have a previous version of the plugin installed, you can try to remove
it entirely before installing the new one.

If you still receive messages about the 2.7.3.RC2 after those steps, a
possibility might be that there is a proxy server of some sort on your
connection that is still serving some outdated files, or some caching that
is interfering with the Eclipse update mechanism; please look for

Miles Sabin might know a few additional tricks. If nothing works, you can
always perform an offline installation by manually downloading the eclipse
plugin archive, unzipping, and installing from there: the link is at
http://www.scala-lang.org/node/94

Sounds like a proxy caching problem to me. I'd try to load the update site in your browser manually and hit refresh from there, and then afterwards try to update from Eclipse again.

Hi.

I can not install Eclipse Scala plugin (neither
http://www.scala-lang.org/scala-eclipse-plugin and
http://www.scala-lang.org/scala-eclipse-plugin-nightly).

The web site either does not have appropriate files or permissions are
too restrictive.

Eclipse's error message is below:

The update site won't load manually from a browser, there is no index.html
or any default page to show. However, loading (and refreshing) this will work:

http://www.scala-lang.org/scala-eclipse-plugin/site.xml

(check with View Source to make sure that the loaded file contains
"2.7.3.final")

The main thing to try is to remove and reinstate the Scala update site
from the update manager ... I believe there's an open Eclipse bug
relating to this.

Cheers,

Miles

Also, are you doing update or re-install? I don't think "update" works very well, if you just go to "Search for new plugins" on the scala update site, that works much better for installing a new version.

Thank you for your hints.

I have already installed it offline (by guessing what JAR URL for
2.7.3 would be :)
I turned out to be a HTTP proxy problem (after explicitly refreshing
site.xml in browser RC reference was replaced by "final" URL).
