409 Conflict during Maven deployment

Udgivelsesdato: Apr 15, 2025
Beskrivelse


The 409 Conflict response is an HTTP status code indicating a request conflict with the current state of the server. This can be triggered due to multiple reasons in the context of Exchange and Maven publishing:

  1.  Asset Already Published with the Same GAV combination
    GAV (Group ID, Artifact ID, Version) uniquely identifies a Maven asset.
    1.  Exchange does not allow republishing an asset with the same GAV unless the original asset is deleted or a version number is changed.
    2. If the same GAV is used in a redeployment or CI/CD pipeline execution, the system returns a 409 Conflict.
  2.  Role or Permission Conflicts on the User Account
    The user or connected app (created by a user) used to publish the asset may have permission constraints or may have exceeded role limits.


What to Check?
To troubleshoot this issue effectively, validate the following:

  1. Deployment Type    - Are all deployments, including redeployments, failing, or only new deployments is failing?
    Authentication - Are all deployments using the same user credentials or connected apps?
Løsning
  1. If the issue occurs only for a particular application deployment, check if the same GAV combination was previously published to the same Exchange.
    If yes, then change the version or artifact_id to be able to successfully publish the asset to Exchange.
  2. If the issue occurs suddenly across all new and re-deployments on the pipeline, check if the deployments use the same connected app/user credentials. 
    If yes, then the issue is likely due to the user having exceeded the role limit.
    1. This can be confirmed from the Splunk logs for the deployment or by checking the roles assigned to the user from the Platform.

How to resolve the second cause:

There are two main approaches to resolve this error:

✅ Option 1: Delete the automatic Backend Permissions that were added, Using Exchange REST API.

✅ Option 2: Use a Different User or Connected App
If the currently connected app or user account is causing conflicts due to overuse or permission issues:

  • Create a new connected app associated with a different user.
  • Use a different set of user credentials with the required permissions.
  • Reconfigure the deployment pipeline to use the new credentials.

This approach isolates the new deployment from any existing backend conflicts.
