我尝试安装JDK 9 Early access version 172来玩JShell.当我尝试打开一个简单的java文件并在将其添加为片段后执行它时,它只显示了修改后的类Test并增加了片段编号.你能帮我理解我哪里出错了吗？

   1 : public class Test{
        public static void main(String[] args){
                 int i = 1;
                 int j = 2;
             System.out.println("Sum of 1 and 2 is : " + (i+j));
        }
       }

jshell> /1
public class Test{
        public static void main(String[] args){
                 int i = 1;
                 int j = 2;
             System.out.println("Sum of 1 and 2 is : …

这是我使用的代码片段：

HttpClient client = HttpClient.newHttpClient();
HttpRequest request = HttpRequest.newBuilder(URI.create("https://www.google.com")).GET().build();
HttpResponse.BodyHandler responseBodyHandler = HttpResponse.BodyHandler.asString();
HttpResponse response = client.send(request, responseBodyHandler);
System.out.println("Status code = " + response.statusCode());

String body = response.body().toString();
System.out.println(body);

NoClassDefFoundError当我运行上面的代码时，Eclipse抛出HttpClient。但是，当我将jshell与一起使用时，此功能可以完美运行--add-modules=jdk.incubator.httpclient。怎样才能使代码通过Eclipse执行？
