The versions of httpcore and httpclient do not match.

Change the version of httpcore from 4.4.5 to 4.4.4 , and the Maven reference is as follows:

<dependency>
    <groupId>org.apache.httpcomponents</groupId>
    <artifactId>httpclient</artifactId>
    <version>4.5.2</version>
</dependency>
<dependency>
    <groupId>org.apache.httpcomponents</groupId>
    <artifactId>httpcore</artifactId>
    <version>4.4.4</version>
</dependency>
