JMeter - static get method (java.lang.String) not found in class'java.nio.file.Paths'

Question

I am trying to create a JMeter load test. I need a test to take a sample log file and change its name. The only way I could find this is to copy the file to the BeanShell preprocessor, but I get the following error:

ERROR - jmeter.util.BeanShellInterpreter: Error invoking bsh method: evalSourced file: inline evaluation of: ``import java.nio.file.StandardCopyOption; import java.io.IOException; import java . . . '' : Typed variable declaration : Error in method invocation: Static method get( java.lang.String ) not found in class'java.nio.file.Paths'

The code I use is as follows:

import java.nio.file.StandardCopyOption;
import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.Paths;

Path source = Paths.get(vars.get("filename");

String filename = "/Users/GX1/Desktop/jmeter/tmp/Device_"+vars.get("global_counter")+"_upload_"+vars.get("file_counter")+".csv.gz";

Path target = Paths.get(filename);
Files.copy(source, target, StandardCopyOption.REPLACE_EXISTING);
vars.put("filename", filename);

filename, global_counter and file_counter are jmeter variables.

Does anyone know why I am getting this error? The beanshell preprocessor doesn't work the way I'm trying to use it?

, , varargs. :

Path target = Paths.get(filename, new String[0]);
