== Build Scripting

A build script is made up of zero or more statements and script blocks:

[source]
----
println(project.layout.projectDirectory);
----

Statements can include method calls, property assignments, and local variable definitions:

[source]
----
version = '1.0.0.GA'
----

A script block is a method call which takes a closure/lambda as a parameter:

[source]
----

		if cipherSuite.id == id {
			return cipherSuite
		}
	}
	return nil
}
