@mrkanaly I had a similar issue. Putting the following in my .vimrc allows me to type arcl to get the same behavior as the old arc land command:

Thanks for the thought. There's 2 issues with this solution. The first is, as you mention, that the result doesn't get uploaded to the server. The 2nd is that there's no enforcement: developers can still run "arc diff" to create a diff that has lint errors and nobody would know. What I'm looking for is a way to efficiently run checkstyle for each new diff. Ideally the results of the checkstyle run would be sent to the server but I'd settle for a solution that simply gives the dev and error message and bails.

I just found this bug because I have exactly the same problem and would love to see this fixed.
