commons-lang3-3.1-bin.zip从commons.apache.org下载并解压到带有 java 的文件夹jdk/lib。我需要从这个库中导入秒表。如何为 IntelliJ IDEA 做到这一点？
Update:
Why can't intelliJ just add pom.xml to existing project without trying to delete it?
更新：为什么 intelliJ 不能将 pom.xml 添加到现有项目而不尝试删除它？
Solved this way:

Downloaded a lib from http://commons.apache.org/intelliJ > Project Structure > Dependencies> + > Library > path to lib from commons.apache.org
从http://commons.apache.org/intelliJ> 项目结构 > 依赖 > + > 库 > 从 commons.apache.org 到 lib 的路径下载了一个库

If you can use Mavenor Gradle, then you can include the library as a dependency:
如果您可以使用Maven或 Gradle，那么您可以将库作为依赖项包含在内：
$ tree
.
|-- pom.xml
`-- src
|-- main
| `-- java
| `-- test
| `-- App.java
`-- test
`-- java
`-- test
`-- AppTest.java
7 directories, 3 files
pom.xml
pom.xml
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

IntelliJ automatically adds the dependencies to the classpath.
IntelliJ 自动将依赖项添加到类路径。
If you open the pom.xml file as a new project in IntelliJ, the dependency will automatically be added to the classpath.
如果在 IntelliJ 中将 pom.xml 文件作为新项目打开，则依赖项将自动添加到类路径中。

Otherwise, if you edit your project settings in IntelliJ, go to the modules section, and then the dependencies tab. You can add your dependencies there. See here.
否则，如果您在 IntelliJ 中编辑项目设置，请转到模块部分，然后转到依赖项选项卡。您可以在那里添加您的依赖项。见这里。
