As far as I can tell, it is not directly supported, but you can override existing minimizer and just disable minimisation for particular files, like that:
In your *Module class add necessary contribution @Contribute(ResourceMinimizer.class) @Primary public static void overrideJavaScriptMinimizer(final MappedConfiguration<String, ResourceMinimizer> configuration) { configuration.overrideInstance("text/javascript", MyGoogleClosureMinimizer.class); } and define your minimisation class by extending GoogleClosureMinimizer and overriding "isEnabled()" method with appropriate logic to disable minimisation for specific files public class MyGoogleClosureMinimizer extends GoogleClosureMinimizer { @Override protected boolean isEnabled(final StreamableResource resource) { return super.isEnabled(resource) && !resource.getDescription().endsWith("/compatibility.js"); } } Notes: - I have not tested this example code, so you might fix some details, but I know that something similar should work (I wrote my custom JavaScript minimizers for Tapestry 5.4); - GoogleClosureMinimizer is part of Tapestry's internals, so be warned that it might require extra porting to new Tapestry's versions; - alternative approach is to replace global ResourceMinimizer service (see org.apache.tapestry5.internal.services.assets.MasterResourceMinimizer for default implementation) and your own logic to decide if minimisation should be performed.
