How to ignore SSL certificate errors in Apache HttpComponents HttpClient 5.1

How do I bypass certificate verification errors with Apache HttpComponents HttpClient 5.1?

I've found a working solution to bypass such errors in HttpClient 4.5 that suggests customizing HttpClient instance:

HttpClient httpClient = HttpClients
            .custom()
            .setSSLContext(new SSLContextBuilder().loadTrustMaterial(null, TrustAllStrategy.INSTANCE).build())
            .setSSLHostnameVerifier(NoopHostnameVerifier.INSTANCE)
            .build();

But it is not applicable to HttpClient 5.1, as setSSLContext and setSSLHostnameVerifier methods do not exist in HttpClientBuilder (which HttpClients.custom() returns).

There are several specialized builders in HC 5.1 that can be used to do the same:

CloseableHttpClient httpclient = HttpClients.custom()
        .setConnectionManager(PoolingHttpClientConnectionManagerBuilder.create()
                .setSSLSocketFactory(SSLConnectionSocketFactoryBuilder.create()
                        .setSslContext(SSLContextBuilder.create()
                                .loadTrustMaterial(TrustAllStrategy.INSTANCE)
                                .build())
                        .setHostnameVerifier(NoopHostnameVerifier.INSTANCE)
                        .build())
                .build())
        .build();
