How to call a gradle method from a groovy script

Question

Is it possible to call a 'ext.' gradle method from a groovy script?

Here is the an example of a gradle ext.method I am trying to call (File: codec.gradle)

ext.encrypt = { param ->
  generateKey()
  String encryptedMessage = encryptAES(param)

  println("--ENCRYPTION--")
  println("password: "+param)
  println("key: "+key)
  println("Encrypted message: "+encryptedMessage)

  return encryptedMessage
}

What i want to do is call it from a groovy script like this one: (File: TestGradleReference.groovy)

I am imagining something like this

apply from: "script/codec.gradle"
String encryptVal = project.encrypt('password')
println("Encrypted value: " + encryptVal)

however this doesn't work

What is the best way (if possible) to call a gradle method from a groovy script?

Answer 1

This is actually not possible

ext.encrypt

are only accessible from gradle files
