Re: [tycho-user] Side-effects of using "mvn clean verify" over "mvn clea

yes, I agree that "mvn clean verify" is the Right Thing^TM in a CI
setting. I was just wondering whether Tycho would "break", as I wasn't
sure whether tycho-p2-plugin:update-local-index had any side-effects I
wasn't aware of. But apparently it's no worse than the good ol'
install:install. ;-)

I'll give -Dtycho.localArtifacts=ignore a try. Sounds exactly like the
safety net needed to prevents an accidental "mvn clean install" to wreak
havoc with your CI build. :-)

Many thanks.
