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

Executing System.getConsole() from Gradle when org.gradle.daemon property is true, or when it's executed from an IDE like IntelliJ or Android Studio it returns null. So for example do System.console().readLine() becomes not possible.

Furthermore starting from Gradle 3.0 gradle.daemon is turned on by default.

Then instead of a workaround to use System.getConsole() I purpose an alternative, use ant.input like so:

task avoidNullOnConsole << {
    ant.input(message: 'Enter keystore password:', addproperty: 'userInputPassword', defaultValue : '1234')
    def password = ant.properties.userInputPassword
}

In this case ant.input shows the message and adds the user input in ant.properties using as a property name the value defined in addProperty. If there is no user input then the value defined in default attribute is used.

Once executed you can get the user input using ant.properties.yourProperty or ant.properties['yourProperty'].

You can check the rest of the ant.input attributes here.

Note: If you want to use ant.input multiple times take in account that you cannot override and existing property so addProperty attribute must be different for each one.
