The parameter matcher anyLong() does not match the long type

why no?

Is there a reason why you actually use Mockito instead of the integrated mocking / stubbing?
Besides that, executing this works fine here, so you would need to provide an MCVE to show what is not working:

@Grab("org.mockito:mockito-core:5.7.0")
import static org.mockito.Mockito.*
@Grab("org.spockframework:spock-core:2.3-groovy-4.0")
import spock.lang.Specification

class Foo extends Specification {
  interface Mapper {
    boolean tryLockTimeout(String lockKey, long waitTime, long leaseTime) throws InterruptedException;
  }

  def foo() {
    given:
    def mapper2 = mock(Mapper)

    when:
    when(mapper2.tryLockTimeout(anyString(), anyLong(), anyLong())).thenThrow(new InterruptedException("error"))
    mapper2.tryLockTimeout("", 0, 0)

    then:
    thrown(InterruptedException)
  }
}

Without Mockito, this is also working just fine:

@Grab("org.spockframework:spock-core:2.3-groovy-4.0")
import spock.lang.Specification

class Foo extends Specification {
  interface Mapper {
    boolean tryLockTimeout(String lockKey, long waitTime, long leaseTime) throws InterruptedException;
  }

  def foo() {
    given:
    Mapper mapper2 = Mock()

    when:
    mapper2.tryLockTimeout(*_) >> { throw new InterruptedException("error") }
    mapper2.tryLockTimeout("", 0, 0)

    then:
    thrown(InterruptedException)
  }
}
