Telling if a method was declared using "a string"

For DSL purposes I want to detect methods defined like:

  def "methodName"() {}

or

  def "This is another method name"() {}

Is there any way to do that using reflection?

This information is not available at runtime. Even with an AST transformation, you would not be able to figure out that the method was defined using a string.

For this, you would have to write your own AntlrParserPlugin and use it using a custom CompilerConfiguration. Then in methodDef from AntlrParserPlugin, when the name of the method is parsed, you could check that the character before the name is a double quote. If a double quote is found, then add a custom annotation to the generated MethodNode, so that the information is available at runtime...
