Mockito Matcher parameters showing as undefined

I am trying to Mock a method contained in the Main class of an application. I'd like to test that when all parameters are submitted successfully, the application calls the correct method, uploadFiles. The when - thenReturn pair is shown below:

NrClient nrClient = (NrClient)Mockito.mock(NrClient.class);
Mockito.when(nrClient.uploadFiles("DF49ACBC8", anyList(), "dl")).thenReturn("");

This shows as a runtime exception: "The method anyString() is undefined for the type MainTest." I have the imports:

import org.mockito.Mockito;
import org.mockito.Matchers;

So why would this method be undefined? Is there an issue in my implementation?

I have also tried anyString() and anyInt() with the same result.

Use the below import

import static org.mockito.ArgumentMatchers.*;

Avoid to use Matchers class because it is now deprecated in order to avoid a name clash with Hamcrest org.hamcrest.Matchers class.

You should be getting it as a compile-time error, not an exception (unless the actual exception is that you've got an unresolved compile-time error).

Just importing org.mockito.Matchers means you can use the name Matchers to mean org.mockito.Matchers anywhere in the class. If you want to import the methods, you need a static wildcard import:

import static org.mockito.Matchers.*;

Or specific methods:

import static org.mockito.Matchers.anyString;
import static org.mockito.Matchers.anyList;

Or you could just qualify the method name in the calling code instead:

Mockito.when(nrClient.uploadFiles("DF49ACBC8", Matchers.anyList(), "dl"))
       .thenReturn("");
