Hi,

Here is the Maven dependency for Apache HttpClient version 4.0-alpha3:

<dependency>
    <groupId>org.apache.httpcomponents</groupId>
    <artifactId>httpclient</artifactId>
    <version>4.0-alpha3</version>
</dependency>

If you are using Gradle then you use the following dependency:

implementation group: 'org.apache.httpcomponents', name: 'httpclient', version: '4.0-alpha3'

Thanks
