How could be simply passed arguments to the Gradle build

build.gradle

task args 
args.map = [:]

tasks.addRule("Pattern: <property>=<value>: Passes arguments to the scripts") { String taskName ->
    def match = taskName =~ /(.*?)=(.*?$)/
    if(match){
	    args.map[match[0][1]] = match[0][2]   
    	task(taskName) << {
    		println "Used to pass value ${match[0][2]} to args.map.${match[0][1]}"
    	}
    }
}

task testaArgs(dependsOn: args) << {
	if(args.map){
		println "Arguments passed:"
		args.map.each{ property, value ->
			println "\t $property=$value"
		}
	} else {
		println "No arguments passed!"
	}
	if(args.map.plugin){
		println "Plugin: $args.map.plugin"	
	} else {
		println 'No plugin selected'
	}
}
