Sometimes the download server fails. Is this problem reproducible when you try the next day? In any case, this isn't an JDT question, so better to use the Oomph forum.

looks like an oomph (or p2? or releng?) question to me:
- someone is trying to download http://download.eclipse.org/oomph/updates/milestone/latest/content.xml
- the repo only contains http://download.eclipse.org/oomph/updates/milestone/latest/compositeContent.jar

FYI. Actually, p2 will generally try to download various "extensions" from that location, i.e, p2.index, content.xml, content.xml.xz, content.jar, compositeContent.xml, site.xml, and so on. It will use the p2.index to determine the best order to try, but if all of them fail (because of a network error, server error, proxy access error), it will report the first one (other than p2.index, which is optional and only for optimization of the search) that produces as failure exception. So it seems clear that if there is a complaint about content.xml at that location, which doesn't exist, because it's a composite, that a general failure to access any files at this site (including the p2.index) has occurred.

I knew about the various extensions approach, but I wasn't aware that the error message by p2 is agnostic to this approach.
=> https://bugs.eclipse.org/512063
It least we now know how to read p2, thanks Smile
