Hi Jerome,

I actually ran into this exact problem some time ago in attempting
to do roughly the same thing. My issue was that I was using a very
old cache, and the repository metadata changed slightly (likely went
from being regular p2 repo to being a composite repo) causing Tycho's
cache manager to fail to find the proper path.

I was still a bit confused about why it had worked on another machine
but I can see that the p2 repo in the 0.16.0 tag (tycho.target) no
longer exists and the one in tycho-surefire/pom.xml was a composite
(debugging the code revealed that it was expecting it to be just a
regular repo).

In my case I needed to update the p2 repos used (I think just
the ones in tycho.target and tycho-surefire/pom.xml) and that allowed
me to do a build offline.

Hope this helps,
