Java 使用Maven构建Hadoop时出错

我正在使用Maven构建Hadoop项目。我面临以下错误

[错误]未能在hadoop minikdc项目上执行目标：无法解析项目org.apache的依赖项。hadoop:hadoop minikdc:jar:3.0.0-SNAPSHOT:find org.apache.directory.jdbm:apacheds-jdbm1:bundle:2.0.0-M2 in缓存在本地存储库中，在经过central的更新间隔或强制更新之前，不会重新尝试解析

有人能帮我吗？

这与Maven用来更新本地存储库中的依赖项有关。一种解决方案是尝试手动删除本地repo中包含依赖项

org.apache.directory.jdbm:apacheds-jdbm1:bundle:2.0.0-M2

的目录，然后重新启动构建

您还可以通过将

-U

传递给Maven来强制更新所有依赖项，例如：

---

mvn clean install-U

如果此依赖项是私有的，则需要将相关信息添加到~/.m2/settings.xml中的maven设置文件中，从您的语句中可以看出，您无法解析project org.apache.hadoop:hadoop minikdc:jar:3.0.0-SNAPSHOT的依赖项。好的，我认为这是你的maven代理错误，你不能下载这个jar。请检查您的代理，然后再次检查。请到办公室去。使用~/.m2/settings.xml修改您的设置

像这样

<proxy>
  <id>optional</id>
  <active>true</active>
  <protocol>http</protocol>
  <username></username>
  <password></password>
  <host>child-prc.intel.com</host>
  <port>913</port>
  <nonProxyHosts>local.net|some.host.com</nonProxyHosts>
</proxy>

可选择的
真的
http
child-prc.intel.com
913
local.net | some.host.com

---

请发布您的pom.xml，而且正如错误所述，您要查找的依赖项不在指定的url位置。我已粘贴了pom.xml。请让我知道问题是什么重复问题，请参阅：此问题也称为错误：
