Grails yui-minify-resources and lesscss-resources conflict

Question

I have my grails application that use lesscss-resources plugin (v 1.3.0.3). I would like to use also the yui-minify-resources plugin (v. 0.1.5). I installed the plugin using:

grails install-plugin yui-minify-resources

But now when I try to start the application I have an exception:

2012-10-15 12:58:48,901 ERROR org.codehaus.groovy.grails.plugins.DefaultGrailsPluginManager  - Error configuring dynamic methods for plugin [resources:1.1.6]: java.lang.NoSuchMethodError: org/mozilla/javascript/Parser.parse(Ljava/io/Reader;Ljava/lang/String;I)Lorg/mozilla/javascript/ScriptOrFnNode;

I think I have this error due the fact that (how the documentation says) YUI minify use an alternative version of Rhino, that is a dependency of lesscss resources plugin.
I tried to exlcude the dependency, but just tried 'cause it seems don't work.
Here is my Config.groov:

plugins{
    compile (":lesscss-resources:1.3.0.3"){
        excludes 'rhino:1.7R3'
    }
}

Does someone has managed the same situation?

I have fixed this problem putting the rhino dependency directly in the lib folder. You can download it from https://developer.mozilla.org/en-US/docs/Rhino/Download_Rhino
