org.apache.httpcore.HttpRequest 依赖哪个jar包？

import org.apache.httpcore.HttpException;
import org.apache.httpcore.HttpRequest;
import org.apache.httpcore.HttpResponse;
import org.apache.httpcore.entity.StringEntity;
import org.apache.httpcore.protocol.HttpContext;

请问引入这个几个类，需要依赖哪个JAR包？

建议你使用maven来管理依赖
