问题描述
我想把jar类文件读入我的eclipse。假设我编写了以下代码:
I want to read jar class files into my eclipse. Suppose I wrote the following code:
List list = new ArrayList();
当我按住Ctrl键时,它会显示两个选项。其中一个选项是Open Declaration,它将显示List接口中的方法。但当我点击它时,它显示未找到源。我已经添加了 java-util-1.8.0.jar
,但它仍然不起作用。
我做错了什么?
When I ctrl click on List, it shows two options. One of the option is Open Declaration which will show the methods in List interfaces. But when I click it it shows source not found. I've added java-util-1.8.0.jar
to it but still it won't work.What am I doing wrong?
推荐答案
为了查看 JDK的源代码
在eclipse中你应该将 JDK
路径而不是 JRE
添加到你的工作区或特定的项目SDK。我假设您是开发人员,并且已在系统上安装 JDK
。
In order to see the source codes of JDK
in eclipse you should add JDK
path instead of JRE
to your workspace or for a specific project SDK. I assume you are a developer and you've installed JDK
on your system.
要做到这一点:
- 右键单击并在项目中选择属性(或按 + )。
- 从左侧树状菜单中选择 Java构建路径
- 在右侧选择库
- 选择 JRE系统库
- Right click and select Properties (or press +) on your project.
- From the left tree styled menu select Java Build Path
- On the right select the Libraries
- Select the JRE System Library
- 从右侧按钮单击编辑,然后编辑路径从
JRE
位置指向文件系统中的JDK
位置。
- From the right side buttons click on edit, and edit the path from
JRE
location to points to theJDK
location in your file system.
- 然后点击完成和所有打开的对话框的OK按钮保存配置,然后设置为。
- Then click on Finish and the OK buttons of all opened dialogs to save the configurations and you set to go.
希望这会有所帮助。
