YUICompressor tries to compress minified resources

Hello,

we enabled production mode in our application.
The Tapestry YUICompressor doesn't seem to recognize already minified JS or CSS files and tries to compress them.
This results in Exceptions like this one:
ERROR] AssetsModule.ResourceMinimizer JavaScript compression problems for resource context:bootstrap/js/bootstrap.min.js:
[ERROR] AssetsModule.ResourceMinimizer String index out of range: 40264
java.lang.StringIndexOutOfBoundsException: String index out of range: 40264

        at com.yahoo.platform.yui.compressor.JavaScriptCompressor.<init>(JavaScriptCompressor.java:533)
        at org.apache.tapestry5.internal.yuicompressor.JavaScriptResourceMinimizer.doMinimize(JavaScriptResourceMinimizer.java:148)

        at org.apache.tapestry5.ioc.internal.OperationTrackerImpl.invoke(OperationTrackerImpl.java:74)

Can we set some options for the Compressor? How do we prevent this error?

AW: YUICompressor tries to compress minified resources

Hello,

would I be able to decorate the YUICompressor with my own implementation which checks if the file is already minified?
Or could I configure the YUICompressor to exclude files?

Regards,
Daniel P.

Tapestry is not quite smart enough to know that .min.css means a minimized CSS file.

You should have access to the non-minimized CSS file, so change it from "context:bootstrap/bootstrap.min.css" to "context:bootstrap/bootstrap.css"
(or equivalent).

The whole concept of Tapestry doing the minimization is to simplify the developer; it's always the same file, but in production mode it gets all the desirable extras (minimization, etc.).
