Let's move our InfoTask to the buildSrc directory of our project. We first create the buildSrc/src/main/groovy/sample directory. We create a file named InfoTask.groovy in this directory, with the following code:

package sample

import org.gradle.api.*
import org.gradle.api.tasks.*

class InfoTask extends DefaultTask {

    String prefix = 'Current Gradle version'

    @TaskAction
    def info() {
        println "$prefix: $project.gradle.gradleVersion"
    }
}

Notice that we must add import statements for the classes of the Gradle API. These imports are implicitly added to a build script by Gradle, but if we define the task outside the build script, we must add the import statements...
