Filter only one file

[Mathieu Leclaire]

Hi,
I developp an application based on OSGi and I use the plugin sbt-osgi.
One of my OSGi projects depends on a jar containing a lot of javascript files (it comes from http://www.webjars.org/ ) stored in META-INF/xxx/yyy
The problem is I just need one or two files in that jar and I can't filter it to only get this file.

This command on my sbt OSGI project does not give me the ace.js file: META-INF.resources.webjars.ace.01.08.2014.src-min.ace.js, so that I need to get all the src-min directory, which contains it!

Is there a way to filter only one file and not a whole directory ?

Thanks
Mathieu
