====

The closure passed to the `initscript()` method configures a link:{javadocPath}/org/gradle/api/initialization/dsl/ScriptHandler.html[ScriptHandler] instance.
You declare the init script classpath by adding dependencies to the `classpath` configuration.

This is the same way you declare, for example, the Java compilation classpath.
