Re: [m2e-dev] testing m2e conectors

Using remoterepo actually makes the tests execute much faster.
As for being self-contained, I'm using explicit target platform for 
tycho build and it accesses the remote P2 repositories on each build, 
and if the network is down, the build fails.
By the way, repository access takes a really long time, about 90s in my 
case. From what I've read there are problems in Tycho/P2 (bugs 344664, 
347477) that cause much more network traffic than necessary. I need to 
search Tycho docs & mailing lists for possible workarounds. If someone 
could point me to some useful resources, I'd appreciate it :)

regards,
Rafał
