【问题解决】mvn deploy出现401错误

mvn deploy出现401错误

问题

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-deploy-plugin:2.8.2:deploy (default-deploy) on p

panda-config-1.0.0-20200223.035607-1.jar with status code 401 -> [Help 1]

原因

一般报401这个错，是因为没有权限，没权限的话，大部分都是因为密码错了导致，或者这个账号本身就没有传jar的权限，一般是maven目录conf的setting.xml里没有配置认证，查看maven的config路径下的settings.xml，查看是否设置了用户名和密码。

解决

在.m2/settings.xml中的server节点下设置用户名和密码。

<server>
  <id>nexus-releases</id>
  <username>admin</username>
  <password>密码</password>
</server>

<server>
  <id>nexus-snapshots</id>
  <username>admin</username>
  <password>密码</password>
</server>

在pom.xml文件中添加

<distributionManagement>
    <repository>
        <id>nexus-releases</id>
        <name>Nexus Release Repository</name>
        <url>http://ip:8081/repository/maven-releases/</url>
    </repository>
    <snapshotRepository>
        <id>nexus-snapshots</id>
        <name>Nexus Snapshot Repository</name>
        <url>http://ip:8081/repository/maven-snapshots/</url>
    </snapshotRepository>
</distributionManagement>

重新执行mvn deploy
