我在部署构件至 maven nexus 私服时，有时会出现 Failed to deploy artifacts: Failed to transfer file: … Return code is: 4XX, ReasonPhrase: … 类似这样的错误，那么这些错误是怎么产生，又如何解决呢？我在此将自己在部署过程中遇到的错误整理汇总一下，供大家参阅，希望对大家有所帮助。

　　一、错误的请求。Return code is: 400, ReasonPhrase: Bad Request.

　　400错误的含义是“错误的请求”，在这里的原因是往往是没有部署到nexus的仓库中。产生原因有如下两种：

　　1、部署仓库错误：

　　前面的博文有讲过 Nexus 私服有三种仓库类型：Hosted、Proxy和Virtual，另外还有一个 group （仓库组）用于对多个仓库进行组合。部署的时候只能部署到 Hosted 类型的宿主仓库中，如果是其他类型就会出现这个 400 错误。若是出现这个错误，只需修改 POM 文件中的部署仓库到对应的宿主仓库即可解决此问题。

　　2、宿主仓库不允许重复部署：
　　默认情况下重复部署构件到 Releases 仓库中也会出现 400 错误，原因是 Nexus 私服中 Releases 仓库默认的 Deployment Policy 是 “Disable Redeploy”，所以当你重复部署构件至 Releases 宿主仓库时就会出现这个 400 错误。出现这个问题，只需要将宿主仓库的 Deployment Policy 改为 “” 即可解决，解决方法如下所示：

　　二、未认证或认证不通过。Return code is: 401, ReasonPhrase: Unauthorized.

　　出现这种错误，原因如下所示：

　　1、是未配置 Nexus 私服用户信息，或配置的账号、密码错误，均会出现 401 的错误，解决方法就是修改 maven settings.xml 配置文件，添加如下信息即可解决问题。　　

  1. <?xml version="1.0" encoding="UTF-8"?>
  2. <settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
  3.         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  4.         xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">
  5.     ...
  6.     <servers>
  7.         <!-- Nexus 构件部署用户信息 -->
  8.         <server>
  9.             <id>nexus-releases</id>
  10.             <username>fanfengping</username>
  11.             <password>密码</password>
  12.         </server>
  14.         <server>
  15.             <id>nexus-snapshots</id>
  16.             <username>fanfengping</username>
  17.             <password>密码</password>
  18.         </server>
  20.     </servers>
  21.     ...
  22. </settings>

复制代码

　　2、是 maven 项目工程 POM 文件中配置的 Nexus 私服宿主仓库的 project.distributionManagement.[repository|snapshotRepository].id 在 maven settings.xml 中配置的宿主仓库 settings.servers.server.id 不存在，统一二者的 ID 后，即可解决此问题。

　　三、连接失败。Connection refused: connect. 或 Return code is: 405

　　出现这种错误，肯定是 POM 文件中配置的 url 错误，认真检查一下 url 是否正确，然后订正一下，重新部署即可。

　　

　　四、缺失私服仓库连接配置。Deployment failed: repository element was not specified in the POM inside distributionManagement element or in -DaltDeploymentRepository=id::layout::url parameter

　　具体提示信息如下所示：

  10.         or in -DaltDeploymentRepository=id::layout::url parameter -> [Help 1]

  16. [ERROR] [Help 1] http://cwiki.apache.org/confluence/display/MAVEN/MojoExecutionException

　　此问题是因 POM 文件遗漏了 Nexus 私服连接配置导致的，在 POM 文件中添加 distributionManagement 节点或者在命令行执行时添加 -DaltDeploymentRepository=id::layout::url 参数即可解决。POM 文件中添加 distributionManagement 如下所示：

  1. <project>
  2.     ...
  4.     <developers>
  5.         ...
  6.     </developers>
  8.     <distributionManagement>
  9.         <repository>
  10.             <id>nexus-releases</id>
  11.             <name>Nexus Releases Repository Pro</name>
  12.             <url>http://localhost:8081/nexus/content/repositories/releases/</url>
  13.         </repository>
  15.         <snapshotRepository>
  16.             <id>nexus-snapshots</id>
  17.             <name>Nexus Snapshots Repository Pro</name>
  18.             <url>http://localhost:8081/nexus/content/repositories/snapshots/</url>
  19.         </snapshotRepository>
  20.     </distributionManagement>
  23.     <dependencies>
  24.         ...
  25.     </dependencies>
  27.     <build>
  28.         ...
  29.     </build>
  30. </project>
