To start off, I know that this may not be Oomph related, but I would like to start off here as the issue occurs during performing Oomph setup tasks.

It seems that

1. if an update site was moved to archive.eclipse.org (e.g. http://download.eclipse.org/graphiti/updates/0.11.1/ )

2. the repository uses mirrors (see content.jar/content.xml):
<property name='p2.mirrorsURL' value='http://www.eclipse.org/downloads/download.php?file=/graphiti/updates/0.11.1/&amp;protocol=http&amp;format=xml'/>


3. There is an Oomph setup that contains a Targlet task that uses the archive repository (see GraphitiArchive.setup attached)

4. Mirrors are enabled during the Oomph task execution

Then the Targlet task will fail with very cryptic error messages:

Turning off Mirrors leads to a successful execution of setup tasks.

The relevant Targlet definition (also in the attachement) is this:

Open a Bugzilla and I'll see if I can find time to have a look.

Thanks for replying, I have checked with "Install new software" and it gives the same error (I didn't know if it would try to use mirrors or not), so the problem is not with Oomph.

I will ask the webmaster as I think this same update site has worked before and move to P2 if it turns out that it may be the culprit.
