Painless scripting error illegal_argument_exception "unexpected token ['('] was expecting one of [{<EOF>, ';'}]"

[ajp]

Running the following painless script against 6.2.4 returns an illegal_argument_exception "unexpected token ['('] was expecting one of [{, ';'}]".

def someVariable = "";

void someFunction(def arg) {
    def someVariable2 = "";
}

someFunction("");

It doesn't error if you use the following script:

void someFunction(def arg) {
    def someVariable2 = "";
}

def someVariable = "";

someFunction("");

I tried searching both the open and closed GitHub issues and the forum here but can't find anything similar mentioned. I was wondering if anyone could:

• point out my error
• confirm this is a bug (by reproducing it) and or
• point me to the bug report

I'm happy to open a new bug report on Github if this turns out to be a real issue.

Thank you for your time.

It seems that all variables need to be declared and defined after all functions. In this case if someVariable is desired inside someFunction then you must pass it in as a parameter. For example:

String someFunction(def arg, String someVariable) {
  return arg + someVariable;
}

String someVariable = "";

someFunction("", someVariable);
