You can simplify that to something like this:

def someMap = [
  (someVariableContainingTheKeyName) : "someValue"
]

There is no need to wrap the key value in a GroovyString. Surrounding any expression with parens in that spot will cause the expression to be evaluated and whatever the expression evaluates to will be the key. If you leave the parens off, the literal "someVariableContainingTheKeyName" will be the key, which is not what you want in this case.
