Compiler error when including Google Maps extern

[jimbo]

I've written a simple javascript file to test compilation of js with
Google Maps API. The compiler is emitting an exception when compiling
with ADVANCED_OPTIMIZATIONS.

The exception is shown below.

java.lang.RuntimeException: java.lang.RuntimeException: INTERNAL
COMPILER ERROR.
Please report this problem.

Node(STRING UNKNOWN_ERROR): ../closure-compiler/contrib/externs/

This is the command I use for compiling.

Compiling with the following command: java -jar ../closure-compiler/
build/compiler.jar --js ../closure-library/closure/goog/base.js --js
hello.js --compilation_level=ADVANCED_OPTIMIZATIONS --externs=../
closure-compiler/contrib/externs/google_maps_api_v3.js --
formatting=PRETTY_PRINT

This is the source file hello.js

goog.provide('example');

example.showMap = function() {
var newyork = new google.maps.LatLng(40.69847032728747,
-73.9514422416687);

var myOptions = {
zoom: 6,
mapTypeId: google.maps.MapTypeId.ROADMAP
};

var map = new google.maps.Map(document.getElementById("map_canvas"),
myOptions);
map.setCenter(newyork);
};

goog.exportSymbol('example.showMap', example.showMap);

I'm using version 374 of the compilation source. Has anyone else faced
similar issue with the gmaps extern? Am I doing something obviously
wrong here? It works un-compiled and with simple compiliation.

Thanks,
James

The Google Maps v3 externs are auto-generated by the maps team and
there is now one for each major version. I'm not sure why there is one
in the contrib/externs folder still as the correct ones now live in /
contrib/externs/maps/. Can you try using the one from that folder and
see if you still have the problem?

And maybe one of the Closure team members can remove the old one that
I manually maintained in the contrib/externs folder?

Thanks for reporting. There's already a fix in progress for the issue.
It should land on svn today.

fwiw, this should be fixed at trunk.

Great. It works now thanks.

I did have to change to use the externs file from maps folder. The one
in contrib is missing MapTypeId.

< f = {zoom:6, mapTypeId:google.maps.MapTypeId.ROADMAP};
---
> f = {zoom:6, a:google.maps.MapTypeId.ROADMAP};
