Custom resource filters
-----------------------
Key: MRESOURCES-128
URL: http://jira.codehaus.org/browse/MRESOURCES-128
Project: Maven 2.x Resources Plugin
Issue Type: New Feature
Reporter: Laurent Martelli
It would be very nice to be able to use some custom resource filters in
addition to properties substitutions. For instance, one may want to "optimize"
PNG images which may contain big proprietary chunks inserted by the editing
software, which are totally useless to the running webapp, but usefull for
editing the image.
Being able to run an external program (like pngcrush in the case mentioned
above) may be an option, but for maximum portability, a Java interface would be
better (filtering PNG chunks is actually easy, and I already have a few Java
classes to do that). The interface could look like this :
public interface ResourceFilter {
void filterResource(InputStream input, OutputStream output, MavenContext
context);
}
The context (I don't know if the class exists) could be used to retrieve the
filter's configuration (some criteria specifying which chunks to include or
exclude, for instance). Or maybe Maven is able to directly configure beans
using their properties.
