How can I create a custom builtType in gradle for android?

Question

I want to create a buildTask that I can use as "gradlew someTask" from the terminal. I basically want to do a few things before I run the build ( like changing versionCode and versionName ). I've tried a few solutions:

someTask.initWith(buildTypes.debug)
someTask{
 ...
}

Doing that, I get no errors while performing a gradle sync but when I run gradlew someTask, it give me an error "someTask not found in project root" and when I run gradlew tasks, someTask does not show up in the list either. How can I fix this?

Any Help is Appreciated.
Thank You

Use this syntax to define your task

}
