在 Eclipse 中 -
1). Put the library in the Java build path
1）。将库放在 Java 构建路径中
Eclipse -> Preferences: Java - Build path - User Libraries push the "New..." button, and in the "User library name:" enter 'appache-commons-lang'.
Eclipse -> Preferences: Java - Build path - User Libraries 按下“New...”按钮，并在“User library name:”中输入“appache-commons-lang”。
Click to select "appache-commons-lang" in the "Defined user libraries" list and then click on the "Add JARs..." button and browse for commons-lang-2.5.jar (in the folder saved earlier) and select it.
在“定义的用户库”列表中点击选择“appache-commons-lang”，然后点击“添加JARs...”按钮，浏览commons-lang-2.5.jar（在之前保存的文件夹中）并选择它。
In the "Defined user libraries", under commons-lang-2.5.jar need to have "Source attachment" and "Javadoc location" specified. For each of them, select it, then push "Edit..." , then "External file" and browse for the corresponding jar (commons-lang-2.5-sources.jar and commons-lang-2.5-javadoc.jar)
在“定义的用户库”中，commons-lang-2.5.jar 下需要指定“源附件”和“Javadoc 位置”。对于它们中的每一个，选择它，然后按“编辑...”，然后按“外部文件”并浏览相应的 jar（commons-lang-2.5-sources.jar 和 commons-lang-2.5-javadoc.jar）
2) In the project add this user library In the Package Explorer right-click on the project name, go to Properties, and select the Libraries tab; click the "Add Library..." button, from the list select "User library" , "Next", mark [x] appache-commons-lang, and click "Finish"
2) 在项目中添加这个用户库 在 Package Explorer 中右键单击项目名称，转到 Properties，然后选择 Libraries 选项卡；单击“添加库...”按钮，从列表中选择“用户库”，“下一步”，标记 [x] appache-commons-lang，然后单击“完成”

You could create a User Libraryusing Apache Commons Lang in Eclipse. User library is a set of jars (these jars can be stored wherever you like). Once defined, user library can be reused in various projects.
您可以在 Eclipse 中使用 Apache Commons Lang创建一个用户库。用户库是一组罐子（这些罐子可以存放在你喜欢的任何地方）。定义后，用户库可以在各种项目中重复使用。
You can find more information how to do this for example here(in an accepted answer).
例如，您可以在此处（在已接受的答案中）找到有关如何执行此操作的更多信息。
After creating a user library you can add it to your projects just as any other library (Project Properties -> Java Build Path -> Libraries -> Add library -> User library -> Next -> choose your library).
创建用户库后，您可以像添加任何其他库一样将其添加到项目中（项目属性 -> Java 构建路径 -> 库 -> 添加库 -> 用户库 -> 下一步 -> 选择您的库）。

You could also do it on a per project basis
您也可以在每个项目的基础上进行
Right click your project -> buildpath -> configure buildpath -> add libraries -> add jar -> select the jar you want to add as dependency to your project
右键单击您的项目 -> 构建路径 -> 配置构建路径 -> 添加库 -> 添加 jar -> 选择要添加为项目依赖项的 jar
(or use maven which does it all for you on creating the eclipse project)
（或使用 maven 在创建 eclipse 项目时为您完成所有工作）
