Unable to run JSDOC

[asrikanth1990]

I am getting following error if i try to run gradle jsdoc

Could not set unknown property 'source' for object of type com.eriwen.gradle.js.JsDocExtension.

I am using gradle 4.0.1.

gradle js 2.14.1

Here is what i have tried

jsdoc {

source = ["src/js/first.js", "src/js/second.js"]
destinationDir = file("${buildDir}/jsdoc")

}
