Nxrm3-maven-plugin + Nexus3 = 401 Not Authorized for user, 404 on tags API for admin

integrations

#1

I’m attempting to push my artifacts to Nexus (3.18.0-01, docker) from a GitLab Runner, but I’m getting the following error:

Failed to execute goal org.sonatype.plugins:nxrm3-maven-plugin:1.0.2:deploy (default-deploy) on project my-project: Get tag was unsuccessful (401 response from server): Unauthorized -> [Help 1]

I followed GitLab guide, which works, and changed the relevant portions to Nexus.
https://docs.gitlab.com/ee/ci/examples/artifactory_and_gitlab/

Here are my maven details using the Sonatype guide (Repository Manager for Maven Plugin):

Tag properties:

<properties>
    <nxrm3.staging.tag>${project.artifactId}-${project.version}</nxrm3.staging.tag>
</properties>

Distribution element:

<distributionManagement>
    <repository>
        <id>my-nexus</id>
        <name>my-nexus</name>
        <url>${env.MAVEN_REPO_URL}/repository/maven-releases</url>
    </repository>
    <snapshotRepository>
        <id>my-nexus</id>
        <name>my-nexus</name>
        <url>${env.MAVEN_REPO_URL}/repository/maven-snapshots</url>
    </snapshotRepository>
</distributionManagement>

Plugin configuration:

        <artifactId>maven-deploy-plugin</artifactId>

        <repository>maven-releases</repository>
        <tag>${nxrm3.staging.tag}</tag>
    </configuration>
</plugin>

[project_folder]/.m2/settings.xml:

<settings xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.1.0 http://maven.apache.org/xsd/settings-1.1.0.xsd"
    xmlns="http://maven.apache.org/SETTINGS/1.1.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
      <servers>
        <server>
          <id>my-nexus</id>
          <username>${env.MAVEN_REPO_USER}</username>
          <password>${env.MAVEN_REPO_PASS}</password>
        </server>
      </servers>
    </settings>

MAVEN_REPO_URL, MAVEN_REPO_USER and MAVEN_REPO_PASS are set in GitLab. The user was added to the admin role to eliminate that as the authorization problem, but that didn’t work. Nexus is running in a docker container and exposed on port 8081, so it’s URL is set to http://myipaddress:8081.

For completeness, here is my .gitlab-ci.yml:

image: maven:3-jdk-8

variables:
  MAVEN_CLI_OPTS: "-s .m2/settings.xml --batch-mode"
  MAVEN_OPTS: "-Dmaven.repo.local=.m2/repository"

cache:
  paths:
    - .m2/repository/
    - target/

build:
  stage: build
  script:
    - mvn $MAVEN_CLI_OPTS compile
  tags:
    - maven
    
test:
  stage: test
  script:

deploy:
  stage: deploy
  script:
    - mvn $MAVEN_CLI_OPTS deploy
  tags:

  only:
    - master

I checked the Log Viewer and there is nothing in there. Below is the entire post build/test output:

#2

In an attempt to further debug, I changed to using the admin user. Not the error changed to 404 as it couldn’t find the tags path.

After checking the API pages in my deployment, sure enough there is no tags path:

#3

So, I guess the question is, is there a way to suppress the plugin from attempting to access the tags path? If not, is the tags API not available with the OSS version?

Hey John,

The Repository Manager for Maven Plugin you referenced and Tagging are both Repository Pro only features.

There is an automated free trial if you want try out your setup with Pro and see if it works how you expect.

Cheers,

Nick
