Body

I am trying to publish a Maven package to a Github repository, for using it in another project as a public package.
When I run mvn clean install javadoc:jar source:jar deploy, I get the following output:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-deploy-plugin:3.1.4:deploy (default-deploy) on project apigatewayfederator: Failed to deploy artifacts: Could not transfer artifact vendorunlockingpatterns:apigatewayfederator:war.asc:1.0.0-20250324.184702-1 from/to github (https://maven.pkg.github.com/vendorunlockingpatterns/apigatewayfederator): Transfer failed for https://maven.pkg.github.com/vendorunlockingpatterns/apigatewayfederator/vendorunlockingpatterns/apigatewayfederator/1.0.0-SNAPSHOT/apigatewayfederator-1.0.0-20250324.184702-1.war.asc 409 Conflict -> [Help 1]

However, some assets are created in Github repository, as you can see here: https://github.com/vendorunlockingpatterns/apigatewayfederator/packages/2445414. Including the apigatewayfederator-1.0.0-20250324.184702-1.war.asc file.

I think that a ,jar file is missing, am I right?

When I try to install in the target project, the message seems to show that Maven is trying to dowload from Maven repository, but the last download line shows that it tried to download from Github.

As it is uploading some files, there are no issues with the credentials.

The personal access token has the following scopes:

• repo

  • repo:status
  • repo_deployment
  • public_repo
  • repo:invite
  • security_events

• write:packages

  • read:packages

• delete:packages

What is missing?
