YuiCompressorTask: "Can't find bundle for base name org.mozilla.javascript.resources.Messages, locale en_US"

Question

I have been using YuiCompressorTask (latest version) on my project for a very long time with no issues. After upgrading to Oracle's Java 1.7 package on OSX, hwoever, it breaks with the following exception (this is for a javascript file; it works fine with a css file):

I can switch back to Apple's Java 1.6 and it works fine. My question is, is there a way around this? I really can't continue on 1.6 any longer.

There is a bug filed for this on GitHub: Can't find bundle for base name org.mozilla.javascript.resources.Messages, locale en_US · Issue #302 · yui/yuicompressor – Castroprauxel

YUICompressor currently only supports ECMAScript 3; there are no current plans to upgrade it to support new ECMAScript constructs due to the engineering work required and the fact that I am the sole maintainer. – Mingo

Answer 1

I decided to switch to the Google Closure Compiler, abandoning the last of the YUI components I've used over the years. I get tons of warnings in the build log, but it does work. sigh

Answer 2

A bit old question, but I run in the same error today.

In my case the problem was a syntax error in my JavaScript, I forgot a } after a cut&paste operation.

I used this online tool (http://refresh-sf.com/) to compress the js file, and it returned some weird error, but more useful than the java exception stack...

Hope this help...

Answer 3

Really old question, but if anyone is still using yui-compress I had the same error and it turned out yui-compress doesn't like trailing comma after arguments in function calls. For example:

foo(a, b, c);

is OK, but

foo(a, b, c,);

is not.

Answer 4

old question but i had to put a comment with my other finds.

It doesnt support define variables with let.

And a new find today, it doesnt allow to define functions with params with a default value

In my case i had to change

function convertDate(inputFormat,type=1)

to

function convertDate(inputFormat,type) {

if(typeof(type)==="undefined")
type=1;

As tip to find why it fails, the best way is to clone the javascript that you are using, and start a new empty, and add blocks until you find which one produces the error.
