Overview

The project-level configuration script that contains task configuration for the current project, written in the Gradle's DSL. The build script may contain any Groovy language element, including:

• println
• Variable declarations.

To make build scripts more concise, Gradle automatically adds the set of default Gradle import statements to the script.

Variables

There are two kinds of variables that can be declared in a build script: local variables and extra properties:

Local Variables

Local variables, which are a feature of the underlying Groovy language, are declared with the "def" keyword. They are only visible in the scope where they have been declared.

def myVariable = "something"
...
println myVariable

Extra Properties

Extra properties can be declared as follows:

...
ext {
    log4jVersion = "2.1.7"
    emailNotification = "build@example.com"
}
...
