I have a Matrix project with one variable called foo. I set two possible values for the variable. Each script creates a bar file in the workspace. The email Subject is set to ${FILE,path="bar"} The resulting emails have the subject ERROR: File 'bar' does not exist

If I change the Subject to ${FILE,path="foo/FOO_VALUE_1/bar"} the file is found the the email subject is a expected.

The email-ext-plugin needs to use the workspace of each matrix configuration as the starting point for the FILE paths (and not the overall project workspace).
