从Maven发布出来的进程:执行插件忽略用户的settings.xml？

Question

根据文档,Maven版本:执行目标检查项目,然后分叉一个新的Maven实例来构建它.由于某种原因,forked实例似乎忽略了用户settings.xml,这导致我的情况出错,因为该文件具有用于在父pom中组成存储库URL的属性的定义.

• 用户的settings.xml
  "nexus"配置文件中始终处于活动状态的属性的定义.

  <profiles>
    <profile>
      <id>nexus</id>
      <properties>
        <dist.url>http://host.com/nexus/content/repositories</dist.url>
      </properties>
    </profile>
  </profiles>
  
  <activeProfiles>
    <activeProfile>nexus</activeProfile>
  </activeProfiles>
  

• Parent的pom.xml
  使用定义的属性来组成存储库的URL.

  <distributionManagement>
    <repository>
      <id>nexus</id>
      <url>${dist.url}/releases</url>
    </repository>
  </distributionManagement>
  

• 执行命令:

  mvn release:perform
  

• 输出(表示已成功检出,构建,测试和打包项目):

  [INFO] Uploading: ${dist.url}/releases/com/acme/access/my-project/1.0/my-project-1.0.jar
  [INFO] [INFO] ------------------------------------------------------------------------

注意分叉的Maven实例如何尝试上传到$ {dist.url},这表示未读取settings.xml中定义的属性.此外,警告消息通知未找到配置文件"nexus".我假设主Maven实例将配置文件信息传递给分叉实例,因此它知道要查找它,但由于它忽略(或没有找到)用户的settings.xml,因此无法找到该配置文件.

我发现绕过这个的唯一方法是settings.xml通过使用-s插件的arguments参数"包装" Maven的命令行参数来手动指定文件的位置,如

mvn release:perform -Darguments="-s C:\Users\theuser\.m2\settings.xml"

插件是否以预期/正确的方式运行？有没有办法将属性定义保留在用户的内部,settings.xml而不必像上面那样指定文件的位置？

更多信息:

• 问题似乎特别是插件没有找到用户settings.xml,因为将配置文件信息复制到全局settings.xml确实会使它工作.

• 用户的settings.xml正确命名/创建,因为运行help:active-profiles表明配置文件被激活.手动构建和部署mvn clean deploy也可正常工作(即,正确计算存储库URL并上载工件).

它不一定是maven-release-plugin中的错误.您似乎遇到了这个Maven错误:MNG-5224 该错误应该在Maven 3.0.4中修复.
