从 Maven 3 部署到 Nexus OSS 2.12 服务器

Deploying to a Nexus OSS 2.12 Server from Maven 3

每当我尝试使用 nexus-staging-maven-plugin 将工件从 maven 3.05 部署到我的 Nexus OSS 2.12 服务器时,我都会收到一条错误消息:

[ERROR] Failed to execute goal org.sonatype.plugins:nexus-staging-maven-plugin:1.6.7:deploy (default-deploy) on project myproject
Failed to deploy artifacts: Could not transfer artifact com myproject:myproject:jar:0.0.1-20160325.164052-1 from/to snapshots (http://nexus.myproject.com/content/repositories/snapshots)
Failed to transfer file: http://nexus.myproject.com/content repositories/snapshots/com/myproject/myproject/0.0.1-SNAPSHOT/myproject-0.0.1-20160325.164052-1.jar. 
Return code is: 401, ReasonPhrase: Unauthorized.

现在奇怪的是,我可以使用带有手动指定凭据的 cURL 部署 pom:

curl -u deployment:deployment123 http://nexus.myproject.com/content/repositories/snapshots/com/myproject/myproject/0.0.1-SNAPSHOT/myproject-0.0.1.pom --request PUT --data @pom.xml

我知道服务器凭据是在我的 ~/.m2/settings.xml 文件中配置的。这是我的:

<?xml version="1.0" encoding="UTF-8" ?>
<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">
    <servers>
        <server>
            <id>nexus</id>
            <username>deployment</username>
            <password>deployment123</password>
        </server>
    </servers>
    <mirrors>
        <mirror>
            <id>central</id>
            <url>http://nexus.myproject.com/content/repositories/central/</url>
            <mirrorOf>*</mirrorOf>
        </mirror>
    </mirrors>
</settings>

请注意,该文件中的 mirrors 部分运行良好 - 当我构建时,maven 使用匿名用户从 nexus 服务器获取我的依赖项。

我在 ~/.m2/settings.xml 文件中配置的凭据与 ID 为 nexus 的服务器相关联。这是我在 pom.xml 文件的 plugins 部分引用的同一台服务器:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-deploy-plugin</artifactId>
    <version>2.8.2</version>
    <configuration>
        <skip>true</skip>
    </configuration>
</plugin>
<plugin>
    <groupId>org.sonatype.plugins</groupId>
    <artifactId>nexus-staging-maven-plugin</artifactId>
    <version>1.6.7</version>
    <extensions>true</extensions>
    <executions>
        <execution>
            <id>default-deploy</id>
            <phase>deploy</phase>
            <goals>
                <goal>deploy</goal>
            </goals>
        </execution>
    </executions>
    <configuration>
        <serverId>nexus</serverId>
        <nexusUrl>http://nexus.myproject.com/</nexusUrl>
    </configuration>
</plugin>

要上传的存储库在我的 pom 文件的 repositories 部分配置:

<repositories>
    <repository>
        <id>snapshots</id>
        <url>http://nexus.myproject.com/content/repositories/snapshots</url>
    </repository>
    <repository>
        <id>releases</id>
        <url>http://nexus.myproject.com/content/repositories/releases</url>
    </repository>
</repositories>

最后,我可以确定 ~/.m2/settings.xml 文件正在被 运行ning mvn help:effective-settings 读取。

当我尝试从命令行运行部署时,我使用命令mvn clean deploy -DskipTests=true

总而言之,我有一台启用了库存部署帐户的 Nexus 服务器。我可以使用该帐户从 cURL 将工件部署到存储库,但是当我尝试使用相同的凭据从 Maven 进行部署时,我收到 HTTP 401。

有人知道为什么这里可能存在差异吗?

我已经能够使用 mvn clean deploy 成功部署仅具有以下内容的工件:

pom.xml

...

<properties>
  <nexus.url>http://mynexus.com:8081/nexus/content</nexus.url>
</properties>

<repositories>
  <repository>
    <id>nexus</id>
    <url>${nexus.url}/groups/public</url>
    <snapshots>
      <enabled>true</enabled>
      <updatePolicy>always</updatePolicy>
    </snapshots>
  </repository>
</repositories>

<pluginRepositories>
  <pluginRepository>
    <id>nexus</id>
    <url>${nexus.url}/groups/public</url>
  </pluginRepository>
</pluginRepositories>

<distributionManagement>
  <repository>
    <uniqueVersion>false</uniqueVersion>
    <id>nexus</id>
    <name>Releases</name>
    <url>${nexus.url}/repositories/releases</url>
  </repository>
  <snapshotRepository>
    <uniqueVersion>false</uniqueVersion>
    <id>nexus</id>
    <name>Snapshots</name>
    <url>${nexus.url}/repositories/snapshots</url>
  </snapshotRepository>
</distributionManagement>

...

settings.xml

...

<servers>
    <server>
        <id>nexus</id>
        <username>deployment</username>
        <password>deployment123</password>
    </server>
</servers>

...

我认为部署到 nexus 的重要部分是 <distributionManagement> 部分。我从来不需要明确声明 maven-deploy-pluginnexus-staging-maven-plugin

希望对您有所帮助!

如果您想使用 Nexus Staging Maven 插件,您需要声明存储库使用暂存端点,或者您需要显式配置暂存配置文件 ID。在您的情况下,您配置了实际的发布存储库而不是暂存端点。

查看 Maven plugin and the staging suite in general. There is also a free video series about it that I recorded as well as a suite of example projects 的文档。
