Maven：无法部署工件，拒绝访问

Question

我有一个Sonatype Nexus服务器，我想部署快照。

这是我的settings.xml文件的片段：

<servers>
  <server>
    <id>test-snapshots</id>
    <username>myname1</username>
    <password>mypasswd1</password>
  </server>
  <server>
    <id>test-releases</id>
    <username>myname2</username>
    <password>mypasswd2</password>
  </server>
</servers>

这是我的pom.xml文件的片段：

<distributionManagement>
  <repository>
    <id>test-releases</id>
    <name>Releases</name>
    <url>https://nxs.company.com/content/repositories/test-releases</url>
  </repository>
  <snapshotRepository>
    <id>test-snapshots</id>
    <name>Snapshots</name>
    <url>https://nxs.company.com/content/repositories/test-snapshots</url>
  </snapshotRepository>
</distributionManagement>

执行mvn deploy（Maven 3.0.3）我收到此错误：

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-deploy-plugin:2.5:deploy 
(default-deploy) on project MyProject: Failed to deploy artifacts: 
Could not transfer artifact com.company.project:MyProject:jar:1.0.0-20121003.154427-1

-> [Help 1]

在我的Nexus日志文件中，我发现没有收到任何凭据，因此稍后会以匿名方式进行尝试，这当然会失败。那么为什么没有凭证传递给Nexus？

Answer 1

对于Nexus中的每个存储库，您真的有不同的用户名/密码吗？这将导致maven http旅行车出现问题，因为jvm会为每台主机缓存凭据，即使maven正确呈现备用凭据，jvm也不会使用它们。解决方法是使用webdav旅行车，因为它使用apache http客户端而不是jdk urlclient。

我们的nexus服务器有多个帐户。在windows user_home / .m2 / settings中有：

    <server>
        <!-- this id should match the id of the repo server in pom.xml -->
        <id>release-nexus</id>
        <username>aa</username>
        <password>AA</password>
    </server>
    <server>
        <!-- this id should match the id of the repo server in pom.xml -->
        <id>snapshots-nexus</id>
        <username>aa</username>
        <password>AA</password>
    </server>

在项目中：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
  <modelVersion>4.0.0</modelVersion>
  <groupId>some.groupid</groupId>
  <artifactId>some-demo</artifactId>
  <version>1.0.0</version>

  <distributionManagement>
    <repository>
      <id>release-nexus</id>  
      <name>Maven Repository Switchboard</name>  
      <url>http://nexus.foo.net/nexus/content/repositories/aa/</url> 
    </repository>

    <snapshotRepository>
      <id>snapshots-nexus</id>  
      <name>Maven Repository Switchboard</name>  
      <url>http://nexus.foo.net/nexus/content/repositories/aa_snapshot/</url>  
    </snapshotRepository>
  </distributionManagement>
</project>

运行mvn deploy

后

输出结果为：

在设置中配置的所有<repository>都与我们在项目pom distributionManagement中使用的不同。如果我把它放在pom中的设置中，就会导致同样的错误forbidden。当我使用用户名和密码aa和AA登录nexus服务器时，我找到了正确的网址，我发现有aa和aa_snapshort。所以我认为PUT操作的权限实际上更加详细。

您需要将'settings'元素作为根
将其放在您的settings.xml文件中：

<settings>
    <servers>
        <server>
            <id>test-snapshots</id>
            <username>myname1</username>
            <password>mypasswd1</password>
        </server>
        <server>
            <id>test-releases</id>
            <username>myname2</username>
            <password>mypasswd2</password>
        </server>
    </servers>
</settings>
