Please help me.

Answer 1

It's working now. Need to edit ${MVN_HOME}/conf/settings.xml instead of /home/{user}/.m2/settings.xml

Answer 2

HTTP 401 is the status code for "unauthorized", which implies that your deployment user isn't authorized to upload artifacts to that particular repository in Nexus. Log in to Nexus and give the deployment user the role(s) required to to change that snapshot repo.

I was missing the<servers> tag on my .m2/settings.xml on Gitlab-ci + MAVEN + Jfrog Artifactory:

My gitlab-ci.yxml

Artifactory_deploy:
  stage: install
  only:
    - desarrollo
  script:
    - echo "Deploying to Artifactory"
    - cd $CLONE_DIR
    - mvn -X deploy

Answer 4

The user that you use for snapshot deployments needs a role with these privileges:

• nx-repository-view-maven2-maven-snapshots-read
• nx-repository-view-maven2-maven-snapshots-edit
• nx-repository-view-maven2-maven-snapshots-add
