[m2] how do i exclude a specific file from a jar

[McGowan, Dan \(NE\)]

Hi,
  Saw an earlier post regarding this on nabble and the suggestion was to use 
<resource><excludes>. However this leaves the resource unavailable for tests. 
In maven1 I was able to not include a file in the jar by specifying 
"maven.jar.excludes=**/myfile.properties" in the project.properties file. Any 
suggestion for accomplishing the same in m2? Thanks,

Dan
