设置正确的类路径来编译和运行Java包？ [英] setting the correct classpath for compiling and running Java packages?

问题描述

我一直使用 Eclipse 最近，其中编译和运行程序很简单。在设置 classpath 时不需要做很多事情。但显然不是这样的情况下，从 commandLine 运行它们。当我尝试从终端 编译时，我有各种错误。我正在粘贴项目 cp125_soln 的我的包结构的图像。现在我想在 com.scg.domain 包中编译 Invoice.Java ，
我试过

I have been using Eclipse lately, where compiling and running the program is very simple. Not much needs to be done in setting the classpath. But apparently that is not the case when it comes to running them from commandLine. when I try compiling from terminal, I am having various errors. I am pasting an image of my package structure of the project cp125_soln. Now I want to compile Invoice.Java in the com.scg.domain package, I tried

javac src/main/java/com/scg/domain/Invoice.java 
src/main/java/com/scg/domain/Invoice.java:17: error: package com.scg.util does not exist
import com.scg.util.StateCode;
.......................//long error message

这意味着我在 classpath com.scg.util。* $ c>。所以我尝试了

This means I do not have com.scg.util.* in my classpath. so I tried

javac -cp src/main/java/com/scg/util/*  src/main/java/com/scg/domain/Invoice.java 
src/main/java/com/scg/util/ListFactory.java:8: error: package org.slf4j does not exist
import org.slf4j.Logger;
                ^
src/main/java/com/scg/util/ListFactory.java:9: error: package org.slf4j does not exist
import org.slf4j.LoggerFactory;
                ^
src/main/java/com/scg/util/ListFactory.java:11: error: cannot find symbol
import com.scg.domain.ClientAccount;
                     ^
  symbol:   class ClientAccount
  location: package com.scg.domain
  ................... // long error message

我阅读了关于 classpath 工作，以及如何在命令行中提供。但是当涉及到包级结构，我找不到一个很好的教程如何 COMPILE和RUN 包。如果可以在编译和运行这些 packages 的正确方式提供一点帮助，它将非常有帮助。

I read different articles on how classpath works and how to provide it in command-line. but when it comes topackage level structures, I am not able to find a good tutorial on how to COMPILE and RUN packages. If a little help could be provided here on the propery way to compile and run these kind of packages, it will be very helpful.

推荐答案

javac src / main / java / com / scg / domain / Invoice.java

javac src/main/java/com/scg/domain/Invoice.java

尝试以下操作：

cd src/main/java
javac com/scg/domain/Invoice.java
