Gradle build null console object

Question

I\'m trying to get my gradle builds to prompt at the console for a password using examples from stack overflow

When I have a statment such as:

def pa         


        

Answer 1

create a simple function to request a password:

import javax.swing.JOptionPane

def askPass() {
  def msg = 'Enter keystore password'
  if (System.console() != null) {
    return System.console().readLine(msg)
  } else {
    return javax.swing.JOptionPane.showInputDialog(msg)
  }
}

or if you want Y/n answer:

import javax.swing.JOptionPane

def ask(msg) {
  if (System.console() != null) {
    return System.console().readLine(msg + ' [y/n]') == 'y'
  } else {
    def res = JOptionPane.showConfirmDialog(null, msg, "Confirm operation", JOptionPane.YES_NO_OPTION)
    return res == JOptionPane.YES_OPTION
  }
}

// usage:

task run() {
  doFirst {
    if (file('out.txt').exists() && !ask('overwrite output?')) {
      System.exit(2)
    }
  }
  ...
}
