Any way to mock Files.write(...) method?

I need help with the unit test case. I want to mock static method write(Path path, byte[] bytes, OpenOption... options) of java.nio.file.Files class.

I tried eg. in that way:

PowerMockito.doReturn(path).when(Files.class, "write", path, someString.getBytes());

In this case the method is not found.

PowerMockito.doReturn(path).when(Files.class, PowerMockito.method(Files.class, "write", Path.class, byte[]
            .class, OpenOption.class));

This time i have UnfinishedStubbingException.

How can I do it correct?
