为什么`HttpClient.newHttpClient()` 不起作用？

Question

I try to learn using HTTPClient . But HttpClient client = HttpClient.newHttpClient(); does not work.

In IntelliJ I've updated my compiler to use Java version 12 and in the pom.xml I've set java.version property to 12.

After I write HTTPClient it gets import sun.net.www.http.HttpClient , and then newHttpClient() method does not work. For this method I need import java.net.http.HttpClient;

This is my pom.xml :

<properties>
    <java.version>12</java.version>
</properties>

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>

You should add this dependency to your POM.xml

 <dependency>
   <groupId>org.apache.httpcomponents</groupId>
   <artifactId>httpclient</artifactId>
   <version>$version</version>
 </dependency>
