I receive the following error when I try to "truffle migrate --network kovan"

Compiling your contracts...

Everything is up to date, there is nothing to compile.

I was expecting a migration to Ethereum's Kovan test net, but received this error instead. I was able to get a little ETH (.001) from the Kovan faucet, but dont suspect a lack of test ETH is the issue here. I also tried "truffle migrate --network kovan --skipDryRun" per other work-arounds that I found on github with no joy.
