Hi guys; I am getting the same issue as I just upgraded my sdk to 1.2.8.
Where can I find the launch configurations for app engine. Please help. I am getting following exception while running the server. Unable to locate the App Engine agent. Please use dev_appserver, KickStart, or set the jvm flag: "-javaagent:<sdk_root>/lib/agent/ appengine-agent.jar" On Oct 20, 3:00 am, Kris Carle <kbca...@gmail.com> wrote: > Hi Keith and Peter, > > This helped me, thanks.
