jsoup未安装在macbook pro上？类测试编译错误jsoup

Question

所以我正在写一个代码，我从一个职位在这里，它使用jsoup ..我也使用MACBOOK专业版10.11.3和我的Java是最新的。

的代码是

package com.stackoverflow.q2835505; 

import org.jsoup.*; 
import org.jsoup.nodes.*; 
import org.jsoup.select.*; 

public class Test { 

public static void main(String[] args) throws Exception { 
    String url = "http://stackoverflow.com/questions/2835505"; 
    Document document = Jsoup.connect(url).get(); 

    String question = document.select("#question .post-text").text(); 
    System.out.println("Question: " + question); 

    Elements answerers = document.select("#answers .user-details a"); 
    for (Element answerer : answerers) { 
     System.out.println("Answerer: " + answerer.text()); 
    } 
} 

} 

我遇到的问题是，我得到的编译错误：

Jack-MacBook-Pro:desktop iModelEx$ javac Test.java 
Test.java:3: error: package org.jsoup does not exist 
import org.jsoup.*; 
^ 
Test.java:4: error: package org.jsoup.nodes does not exist 
import org.jsoup.nodes.*; 
^ 
Test.java:5: error: package org.jsoup.select does not exist 
import org.jsoup.select.*; 
^ 
Test.java:11: error: cannot find symbol 
     Document document = Jsoup.connect(url).get(); 
     ^
    symbol: class Document 
    location: class Test 
Test.java:11: error: cannot find symbol 
     Document document = Jsoup.connect(url).get(); 
         ^
    symbol: variable Jsoup 
    location: class Test 
Test.java:16: error: cannot find symbol 
     Elements answerers = document.select("#answers .user-details a"); 
     ^
    symbol: class Elements 
    location: class Test 
Test.java:17: error: cannot find symbol 
     for (Element answerer : answerers) { 
      ^
    symbol: class Element 
    location: class Test 
7 errors 

所以他这样说，我下载jsoup-1.10.1.jar但我不知道我是否应该把它放在桌面上或放到一个文件夹中？或者以某种方式打开它？我该怎么办？非常感谢！

编辑：这是Jsoup，而不是我的代码中的特定问题，因为所有的错误指向jsoup这显然不是我的java库

您必须下载jsoup正确实施文件。

下载jsoup去你的项目属性 - 后> Java构建路径 - > libraries->添加外部JAR

，然后找到你jsoup.jar刚刚下载。
