英文:
com.opencsv not found when lauched from console
问题
我有一个Maven项目，简单地读取一个CSV文件并将数据写入另一个文件。当我从IntelliJ构建/运行时，它运行良好，但当我从控制台运行$ java read.java时，它会产生以下错误：
src/main/java/read.java:1: error: package com.opencsv does not exist
import com.opencsv.CSVReader;
对于CSVWriter也是同样的情况。
我已经将.jar文件添加到了我的项目中，但并不成功。我如何能够从控制台启动我的应用（这样我就可以在启动时使用参数）？
谢谢

import com.opencsv.CSVReader;
Same thing for CSVWriter.
I added the .jar to my project but it was not successful. How can I launch my app from console (so I can use arguments as I launch it)?
Thank you

你只需要将必要的 JAR 包添加到类路径中。
例如：
java -cp libs/opencsv-5.2.jar read.java
参考：

英文:
You just need to add the neccesary jars to the classpath.
For example:
java -cp libs/opencsv-5.2.jar read.java
