Error Message

Not allowed to define a named function <xxx> within another function. RefId: S06003

Probable Causes

It is not allowed to define a named function within another named function definition. Otherwise, this error will be reported. For example:

def f1() { 
    def f2() { 
        return "Hello" 
    } 
    return f2() 
}

Solutions

• Change the nested named function to an anonymous function (recommended):

  def f1() {
      f2 = def () { // Define an anonymous function
          return "Hello" 
      } 
      return f2() 
      }

• Move the nested function to the global scope:

  def f2() { 
      return "Hello" 
  } 
  
  def f1() {
      return f2() 
  }
