java - 发布 :perform from my maven build 时收到 401 错误代码

Question

我在尝试向 Sonatype 发布新版本软件时遇到错误。我已成功完成 mvn release:prepare 但是当我执行 mvn release:perform 时出现以下错误:

我找到了有关该错误的博客文章，但没有看到任何与我的设置相匹配的内容。

http://blog.sonatype.com/2010/11/what-to-do-when-nexus-returns-401/#.Uv7EYEKwJUI

该帖子引用的设置文件与 pom.xml 中的配置不匹配。但是我在 pom 中没有任何关于部署的内容。我没有配置插件，所以它一定是使用默认插件配置进行发布。据我了解，这是 Maven 发布插件。

此设置过去有效，但我是在另一台机器上执行此操作。我必须在这篇文章之后生成一个新的 gpg 私钥:

http://blog.sonatype.com/2010/01/how-to-generate-pgp-signatures-with-maven/#.Uv2JUkKwJUI

此设置以前有效，但我已转移到新机器上。我确保将 .m2/settings.xml 文件复制到我的 ~/.m2/settings.xml。当然，该私钥与我在旧机器上的私钥不同。但我无法弄清楚为什么这很重要，或者这是否重要。从我读过的内容来看，它只是用于代码签名。不确定如何授权代码签名。

那我错过了什么？为什么这个 401 错误不断发生？

Answer 1

遵循第一个链接中的建议。 401 表示无法对服务器进行身份验证。您声明您没有在 POM 中配置任何内容来支持部署。如果这以前有效，那是不正确的。您的 POM 中是否有分发管理部分？

  <distributionManagement>
    <repository>
      <id>nexus-release</id>
      <name>My Nexus release area</name>
      <url>https://????????</url>
    </repository>
  </distributionManagement>

id 部分必须与 Maven 设置文件中“servers”部分的 id 相匹配。

<server>
  <id>nexus-release</id>
  <username>mark</username>
  <password>mycleartextpasswordconsiderusingmavenbuiltinencryption</password>
</server>

这是“陷阱”，说明了 Maven 如何将目标存储库与用户身份验证凭据相关联。

最后，为了使您的构建使用正确的设置文件，我总是将其作为参数传递给构建:

mvn -s ~/.m2/settings.xml ....

这种方法还可以为不同的项目启用不同的设置文件。

注意

• 第二个链接无关。它涉及签署你的 Artifact 正在发布(以便其他人相信它来自您)。
