trying to push java repo to maven, it keeps giving me 401-UnAuthorized

I'm extracting all the common models from my project, and trying to move them into a separate repository:

<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/maven-v4_0_0.xsd">
  <modelVersion>4.0.0</modelVersion>
  <groupId>com.mua.common</groupId>
  <artifactId>models</artifactId>
  <packaging>jar</packaging>
  <version>1.0-SNAPSHOT</version>
  <name>models</name>
  <url>http://maven.apache.org</url>
  <dependencies>
    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>

      <scope>test</scope>
    </dependency>
    <dependency>
      <groupId>org.projectlombok</groupId>
      <artifactId>lombok</artifactId>
      <version>1.18.22</version>
    </dependency>
  </dependencies>
  <distributionManagement>
    <repository>
      <id>models</id>
      <url>https://nexus.myhost.bd/repository/maven-central/</url>
    </repository>
    <snapshotRepository>
      <id>models-snapshots</id>
      <url>https://nexus.myhost.bd/repository/maven-central/</url>
    </snapshotRepository>
  </distributionManagement>

  <build>
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-deploy-plugin</artifactId>

        <executions>
          <execution>

            <phase>deploy</phase>
            <goals>
              <goal>deploy</goal>
            </goals>
          </execution>
        </executions>
      </plugin>
    </plugins>
  </build>

  <repositories>
    <repository>
      <id>alt-models</id>
      <url>https://nexus.myhost.bd/repository/maven-central/</url>
    </repository>
  </repositories>

</project>

And in my C:\Users\<username>\.m2 folder I've added the settings.xml as well:

<settings>
  <servers>
    <server>
      <id>alt-models</id>
      <username>username</username>
      <password>password</password>
    </server>
  </servers>
</settings>

But whenever I click on deploy from intellij it gives me 401 - UnAuthorized exception.

I'm hosting a nexus to store my packages.

How can I resolve this? What am I doing wrong here?

Update (modified the settings.xml like this):

<?xml version="1.0" encoding="UTF-8"?>
<settings>


  <servers>
    <server>
      <id>models</id>
      <username>username</username>
      <password>password</password>
    </server>
    <server>
      <id>models-snapshot</id>
      <username>username</username>
      <password>password</password>
    </server>


  </servers>
</settings>

But it's still not working

Here is the complete log of failure:

Solution

  • I had to add this under my module's pom.xml under project:

    <distributionManagement>
    <repository>
      <id>models</id>
      <url>https://nexus.myhost.bd/repository/mygroup/</url>
    </repository>
    <snapshotRepository>
      <id>models</id>
      <url>https://nexus.myhost.bd/repository/mygroup/</url>
    </snapshotRepository>
  </distributionManagement>

  <build>
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-deploy-plugin</artifactId>
        <version>3.1.1</version>
        <executions>
          <execution>
            <id>deploy-artifacts</id>
            <phase>deploy</phase>
            <goals>
              <goal>deploy</goal>
            </goals>
          </execution>
        </executions>
      </plugin>
    </plugins>
  </build>

  <repositories>
    <repository>
      <id>models</id>
      <url>https://nexus.myhost.bd/repository/mygroup/</url>
    </repository>
  </repositories>

    And in .settings.xml under ~/m2 (on linux), or in C:\Users\<username>\.m2, I have added this:

    <?xml version="1.0" encoding="UTF-8"?>
<settings>
  <servers>
    <server>
      <id>models</id>
      <username>username</username>
      <password>password</password>
    </server>
  </servers>
</settings>

    And finally, in the project where I want to use I module, I had to add these lines under project:

    
    <repositories>
        <repository>
            <id>models</id>
            <url>https://nexus.myhost.bd/repository/mygroup/</url>
        </repository>
    </repositories>

    Then we can add our dependency in dependencies section, and build it without any error.
