Hi :)

I am receiving the Error message attached below when I try to install Epsilon Core via Help --> Install New Software using the update site (http://download.eclipse.org/epsilon/updates/ )

I am aware that there are other ways to install Epsilon, but for various reasons this would be the best way for me. Any hints regarding possible reasons would be very much appreciated.

Best regards,
Thomas

My Eclipse version:
Eclipse Modeling Tools
Version: 2020-06 (4.16.0)
Build id: 20200615-1200
OS: Windows 10, v.10.0, x86_64 / win32
Java version: 1.8.0_231

Error Message
An error occurred while collecting items to be installed

Hi Thomas,

Please ensure that "Contact all update sites during install to find required software" is ticked. Failing that, you should check that the Orbit repository is in your list of update sites and if it doesn't work, you may need to manually install the following:
org.antlr.runtime 3.5.2 (untick "Show only latest versions")
org.apache.commons.csv 1.4.0.
(In your case, you probably already have ANTLR 3.2.0 so you just need Commons CSV).

This is a known issue which occasionally occurs with the update site manager and Eclipse update sites, unfortunately it seems to be difficult to reproduce consistently and to fix it on our part. Hope that helps.

Thanks,
Sina

I've also updated the Interim site so that CSV is a separate feature, so installing Core / EMF features on a Modeling Tools distribution shouldn't require any dependencies from other update sites
