#### 关键错误信息 ####

*  关键错误信息1： Failed to deploy artifacts
 *  关键错误信息2： Could not transfer artifact com.＊:＊:pom:＊ from/to snapshots (http://dev-mvn.\*\*\*.com/content/repositories/snapshots/)
 *  关键错误信息3： Return code is: 401, ReasonPhrase: Unauthorized. -> \[Help 1\]
 *  提取关键错误信息：Could not transfer …… from/to snapshots …… Return code is: 401, ReasonPhrase: Unauthorized.
 *  很明显了，是由于权限的问题导致服务器拒绝了本次推送。

#### 解决方案 ####

*  检查开发环境使用的maven配置文件
    
     *  我用的是idea
     *  maven配置位置：File/Settings; Build,Execution,Deployment/Build Tools/Maven;
     *  User settings file: D:/java/maven/apache-maven-3.3.9\\conf\\settings.xml
 *  修改settings.xml ，加入如下配置：

<servers>
        <server>
            
            <id>nexus-snapshots</id>
            <username>deployment</username>
            <password>123456</password>
        </server>
        ...
    </servers>

*  再次执行 mvn clean deploy -DskipTests 命令，显示上传成功！

### mvn package、install、deploy命令的区别 ###

#### mvn package 命令：在项目的target目录下生成java包 ####

当我们使用package来打包项目的时候，就会在我们的项目目录下生成一个target文件夹。  
如果是web项目比如MVC项目就会在该文件夹下生成一个war包，放在服务器中的tomcat/webapps目录里即可运行。  
如果是Java项目的话就会在该文件夹下生成一个jar包，放在服务器中指定目录下使用"java -jar jar包名"命令运行。  
一般我们服务器部署服务都是使用package方式打包项目。

#### mvn install 命令: 将java包安装到本地maven仓 ####

使用install方式就是将项目转换成为maven依赖存放在本地maven仓库中。  
就比如我的spring boot项目执行mvn install 命令后，将把jar存在我本地maven仓库中。  
比如我自己配置的maven路径是：D:\\java\\maven\\repository… 。  
一般是多个项目中，例如a项目中使用了b项目的一些方法需要添加b项目作为依赖，此时就需要将b项目使用install方式打包到本地\[maven\]仓库中，以此来给a项目依赖导入调用。

#### mvn deploy 命令：将java包发布到中央仓（注：需要在maven中配置有权限的推送账户名+密码） ####

deploy与install的主要区别就是install是将项目jar包放在本地仓库，而deploy是放在私服仓库。  
在本地的pom文件配置好私服仓库的信息之后，执行deploy命令，可以将maven所打的jar包上传到远程的repository，便于其他开发者和工程共享。  
执行maven deploy命令成功之后，登录私服进行查询，即可看到对应的jar包。

### mvn 跳过测试代码 ###

直接运行上面的命令，默认会执行单元测试代码，跳过单元测试使用如下命令：

1.  mvn -DskipTests
2.  mvn -Dmaven.test.skip=true

#### 区别 ####

*  mvn clean package -DskipTests
    
     *  不执行测试用例，但编译测试用例类，将在target/test-classes目录生成相应的class文件。
     *  使用 mvn package -DskipTests 跳过单元测试，但是会继续编译。
 *  mvn clean package -Dmaven.test.skip=true
    
     *  不执行测试用例，也不编译测试用例类；
     *  使用maven.test.skip不但跳过单元测试的运行，也跳过测试代码的编译;
