Original:

My goal is to play with an end-to-end maven repository deployment and dependency import.

I am working on deploying a maven project(project name my-app) artifact to jFrog and then add the artifact as an dependency to another maven project(project name is my-second-app)

  1. I have setup the jFrog account
  2. Initialized settings.xml under folder ~/.m2/ with the jFrog credentials(username and password) and specified the URL for release and snapshots
  3. I have added the following plugins in project my-app:
        <plugin>
          <groupId>org.apache.maven.plugins</groupId>
          <artifactId>maven-jar-plugin</artifactId>
          <executions>
            <execution>
              <id>make-a-jar</id>
              <phase>compile</phase>
              <goals>
                <goal>jar</goal>
              </goals>
            </execution>
          </executions>
        </plugin>
        <plugin>
          <groupId>org.apache.maven.plugins</groupId>
          <artifactId>maven-install-plugin</artifactId>
          <executions>
            <execution>
              <phase>install</phase>
              <goals>
                <goal>install-file</goal>
              </goals>
              <configuration>
                <packaging>jar</packaging>
                <artifactId>${project.artifactId}</artifactId>
                <groupId>${project.groupId}</groupId>
                <version>${project.version}</version>
                <file>
                          ${project.build.directory}/${project.artifactId}-${project.version}.jar
                      </file>
              </configuration>
            </execution>
          </executions>
        </plugin>
        <plugin>
          <groupId>org.apache.maven.plugins</groupId>
          <artifactId>maven-deploy-plugin</artifactId>
          <executions>
            <execution>
              <phase>deploy</phase>
              <goals>
                <goal>deploy-file</goal>
              </goals>
              <configuration>
                <packaging>jar</packaging>
                <generatePom>true</generatePom>
                <url>https://mycompany.jfrog.io/artifactory/my-app-libs-release</url>
                <artifactId>${project.artifactId}</artifactId>
                <groupId>${project.groupId}</groupId>
                <version>${project.version}</version>
                <file>${project.build.directory}/${project.artifactId}-${project.version}.jar</file>
              </configuration>
            </execution>
          </executions>
        </plugin>
  1. When I run mvn deploy, the projects shows 401 Unauthorized error but the artifact is deployed and can be found in jFrog packages.
  2. I have added the dependency in project my-second-app and the dependency can be downloaded when run mvn install
    <dependency>
      <groupId>com.mycompany.app</groupId>
      <artifactId>my-app</artifactId>
      <version>0.0.6-SNAPSHOT</version>
  </dependency>

Does anyone know what I have been missing? Why I got the 401 unauthorized error? I have added the credentials in settings.xml, my understanding is it is not required to add any credential in project level.

Any help is appreciated, thanks in advance.

CodePudding user response:

Maven is configured with built-in defaults that work in most cases, and the standard Maven-aware repository servers like Nexus and Artifactory will work with them with minimal configuration.

Cut out the custom configuration you have for maven-deploy-plugin and let it use the default setup. Instead, add a distributionManagement section with a repository for your server, and make sure you have matching credentials in your ~/.m2/settings.xml file.
