从 Maven 部署 Nexus 中的工件会出现错误“返回代码是：401”？

Question

我在 Nexus 中部署时收到 401 错误。我没有对已安装的 Nexus 进行任何更改。 Nexus 正在

localhost:8080/nexus

上运行，我可以使用默认用户/密码登录。当我运行时

mvn deploy

我收到此错误。

这是我的 POM。

 <groupId>testproject</groupId>
 <artifactId>testproject</artifactId>
 <packaging>jar</packaging>
 <version>1.0-SNAPSHOT</version>
 <name>testproject</name>
 <url>http://maven.apache.org</url>
 <distributionManagement>
  <repository>
      <id>releases</id>
      <url>http://localhost:8080/nexus/content/repositories/releases</url>
    </repository>
    <snapshotRepository>
       <id>snapshots</id>
       <url>http://localhost:8080/nexus/content/repositories/snapshots</url>
    </snapshotRepository>
</distributionManagement>
<dependencies>
 .........
</dependencies>

和 ~/.m2/settings.xml

<servers>
    <server>
        <id>snapshots</id>
        <username>deployment</username>
        <password>deployment123</password>
    </server>
    <server>
        <id>releases</id>
        <username>deployment</username>
        <password>deployment123</password>
    </server>
</servers>

例外：

Failed to execute goal org.apache.maven.plugins:maven-deploy-plugin:2.7:deploy (default-           deploy) on project testproject: Failed to deploy artifacts: Could not transfer artifact testproject:testproject:jar:1.0-20131213.150615-1 from/to snapshots (http://localhost:8080/nexus/content/repositories/snapshots): Failed to transfer file: http://localhost:8080/nexus/content/repositories/snapshots/testproject/testproject/1.0-SNAPSHOT/testproject-1.0-20131213.150615-1.jar. 
Return code is: 401 -> [Help 1]

请帮助我。

Answer 1

现在正在工作。需要编辑

${MVN_HOME}/conf/settings.xml

而不是

/home/{user}/.m2/settings.xml

Answer 2

HTTP 401 是“未经授权”的状态代码，这意味着您的

deployment

用户无权将工件上传到 Nexus 中的特定存储库。登录到 Nexus 并为

deployment

用户提供更改该快照存储库所需的角色。

Answer 4

用于快照部署的用户需要具有以下权限的角色：

• nx-存储库-视图-maven2-maven-快照-读取
• nx-存储库-视图-maven2-maven-快照-编辑
• nx-存储库-视图-maven2-maven-快照-添加

Answer 5

我在尝试部署到本地 Nexus 服务器时出现问题。状态 401 故障是间歇性的，并且并不总是在同一对象上。我的解决方案是将以下内容添加到我的 pom 中：

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-deploy-plugin</artifactId>
    <version>2.8</version>
    <configuration>
        <retryFailedDeploymentCount>2</retryFailedDeploymentCount>
    </configuration>
</plugin>

设置 retryFailedDeploymentCount 参数会导致插件重试上传所有文件，并在第二次尝试时成功部署所有内容。
