Installing via p2.director no longer working

[msven]

Hello,

Up until recently I used to be able to install EPIC via the following command line command

/opt/eclipse/eclipse -vm /usr/bin/java -noSplash -application org.eclipse.equinox.p2.director -repository http://e-p-i-c.sf.net/updates -i org.epic.feature.main.feature.group

However, I am now getting the following error

!MESSAGE The installable unit org.epic.feature.main.feature.group has not been found.

I've dug around some and from what I can tell the update site has recently changed to a newer format.
For example, as I examine an entry the waybackmachine logged from November 19th 2014 ( https://web.archive.org/web/20141119041012/http://www.epic-ide.org/updates/ ) I see it does not have the artifacts.jar or content.jar files.

Perhaps the new update site format is missing some required files (such as the p2.index file)?

Let me know if I can provide any other useful information or if I should be posting this question somewhere else.

Thanks!

There appears to be a misconfiguration of the web server, which is responding to a request for /updates/p2.index with 302 whereas it should be responding with 404 (interestingly, only to the Java client, not to a normal browser). I opened a ticket with the server admin to fix that.

Please try again, the problem has been fixed.

It worked, thanks for the help and quick reply!
