Setting up IntelliJ IDEA to run Spring Applications with Jetty

- I needed Servlet 3.0 features (like config through ServletContainerInitializer interface), but unfortunately Gradle's Jetty plugin (as of v2.4) uses Jetty 6, so it doesn't support Servlet 3.0. So I'm not bothering.

- Instead, I used the third party plugin gretty:  http://akhikhl.github.io/gretty-doc/Getting-started.html

- Had problems using gretty with the IDEA's Default Gradle Wrapper (gradle 1.8):

Error:Unable to load class 'org.codehaus.groovy.runtime.typehandling.ShortTypeHandling'.
Possible causes for this unexpected error include:

• Gradle's dependency cache may be corrupt (this sometimes occurs after a network connection timeout.)

Re-download dependencies and sync project (requires network)

The state of a Gradle build process (daemon) may be corrupt. Stopping all Gradle daemons may solve this problem.

Stop Gradle build processes (requires restart)
In the case of corrupt Gradle processes, you can also try closing the IDE and then killing all Java processes.
So instead I switched to using Local Gradle Distribution (2.4).

Use gradle appStart to start the server.
Use gradle appStop to stop the server.
