requestFactory(Class<? extends ClientHttpRequestFactory>) in the type RestTemplateBuilder is not applicable

I am using springBootVersion = '2.0.1.RELEASE' on my project. I am trying to write mutual authentication code for that I wrote RestClientCertTestConfiguration class as below. I am getting error on requestFactory. The method requestFactory(Class) in the type RestTemplateBuilder is not applicable for the arguments (HttpComponentsClientHttpRequestFactory) Any suggestion on how to resolve this issue? thanks

    @Configuration
public class RestClientCertTestConfiguration {

    private String allPassword = "mypassword";

    @Bean
    public RestTemplate restTemplate(RestTemplateBuilder builder) throws Exception {

        SSLContext sslContext = SSLContextBuilder
                .create()
                .loadKeyMaterial(ResourceUtils.getFile("classpath:myCerts.jks"), allPassword.toCharArray(), allPassword.toCharArray())
                .loadTrustMaterial(ResourceUtils.getFile("classpath:myCerts.jks"), allPassword.toCharArray())
                .build();

        HttpClient client = HttpClients.custom()
                .setSSLContext(sslContext)
                .build();

        return builder 
                 //error on this line
                .requestFactory(new HttpComponentsClientHttpRequestFactory(client))
                .build();
    }

}

The below method works fine till spring boot 1.x

.requestFactory(new HttpComponentsClientHttpRequestFactory(client))

but in later version of spring boot like 2.x you need to change it to - 

.requestFactory(HttpComponentsClientHttpRequestFactory.class)

or

.requestFactory(() -> new HttpComponentsClientHttpRequestFactory(client))

The requestFactory method takes either the class, or a Supplier<ClientHttpRequestFactory> so you need to do either:

.requestFactory(HttpComponentsClientHttpRequestFactory.class)

or

.requestFactory(() -> new HttpComponentsClientHttpRequestFactory(client))

Presumably the latter, since you want to pass in client.
