How can I write a matcher using Mockito that matches any string except a specific one?

I have tried using some hamcrest matchers to negate and combine other matchers, but the hamcrest matchers all return values of type Matcher<T> which dont work very well with Mockito matchers.

The solution I used:

import static org.hamcrest.CoreMatchers.not;
import static org.mockito.ArgumentMatchers.argThat;

// ...

argThat(not("ExceptionString"))
