shift + alt + x  (brings up popup with run options) => m = maven
OR Window -> Preferences -> General -> Keys   (sort by Binding to see what's already defined)
search filter "maven" -> Run Maven Clean => f9
Running Control + F11 will fail as there is no executable for Eclipse to run
    java.lang.NoClassDefFoundError: com/oxygencloud/sdk/util/MyMain
    Caused by: java.lang.ClassNotFoundException: com.oxygencloud.sdk.util.MyMain
search filter "maven" -> (copy command "Run Maven Build") -> Run Maven Build => f10
(VERIFY IN Run As -> Run Configurations -> Maven Build -> getoxygensession exists with goal package)
NOW, the secret hotkey combo is: F9 -> F10 -> Control + F11
MAKE SURE YOU CAREFULLY CONTROL YOUR PACKAGES AND ACCESS MODIFIERS FOR YOUR DEPENDENCIES
