i.e) when a file found inside a directory with the .doc extension it should proceed to execute steps.

Below code is unable to find the files in .doc format

        when {
            expression
            { 
               return (fileExists("""${Path}/${version}/test/*.doc"""))
            }
        }

Use findFiles, fileExists doesn't support wildcards.

when {
    expression { 
       return (findFiles(glob: "${Path}/${version}/test/*.doc").length > 0)
    }
}
