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>

...
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-plugin
或 nexus-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。
