Upgrade from Tycho 2.6.0 to 3.0.4 => Unresolveable build extension on org.eclipse.platform:org.eclipse.equinox.p2.repository

Hi,

when upgrading from Tycho 2.6.0 to 3.0.4, I get the following error:

I have checked the artifacts of our artifactory, and there are many versions of "org.eclipse.equinox.p2.repository". The latest one 1.4.800. As far as I know, our artifactory is a mirror of maven central, so I do not think that any artifact is missing there.

However, in the output I see the following

So I can see that the download of metadata ended with the version 1.4.0. So no metadata was read for versions 1.4.100, 1.4.200, 1.4.300, 1.4.400, 1.4.500, 1.4.600, 1.4.800. Is this the root of the problem? Can I configure it to retry or somehow solve the issue otherwise?

Thanks

First you can try to pass -U to maven to force an update, second the best it to try with an empty repository (so there are no leftovers) and last you can try to use maven central to make sure its not a problem of your mirror used.
