Gradle: print buildscript dependencies

build.gradle

apply plugin: 'eclipse'
apply plugin: 'maven'

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies { 
        classpath 'org.apache.commons:commons-email:1.2'
    }
}

task printBuildScriptClasspath << {
    println project.buildscript.configurations.classpath.asPath
}

I found out this way by looking at your way to do it:

task buildScriptDependencies(type: org.gradle.api.tasks.diagnostics.DependencyReportTask) {
    configurations = project.buildscript.configurations
}

This is now built into gradle and can be invoked using the buildEnvironment task.
