Nexus repository manager connection setup

Feature availability Package repository integrations are available with Enterprise plans. For more information, see plans and pricing.

Supported projects The Nexus Repository Manager integration supports Node.js (npm and Yarn) and Maven Projects. For Improved Gradle SCM scanning, use the Maven settings.

Connecting Nexus repository manager enables Snyk to resolve all direct and transitive dependencies of packages hosted on the Nexus registry and calculate a more complete, accurate dependency graph and related vulnerabilities.

You can configure these types of Nexus repository manager:

• Publicly accessible instances protected by basic authentication

• Instances on a private network by using Snyk Broker (with or without basic authentication).

Versions supported

• Nexus Repository Manager version 3.0+

• Nexus Repository Manager version 2.15+

These instructions apply to configuring publicly accessible instances. For instructions on configuring a brokered instance, see the setup instructions for Snyk Broker with Nexus Repository Manager.

Set up publicly accessible instances

1. Navigate to Settings > Integrations > Package Repositories > Nexus

2. Verify that you see the screen to configure Nexus.

Configure Nexus

On the page to configure Nexus, enter the information for the version you are using.

Nexus 3

• Enter the URL of your Nexus instance; this must end with /repository

• Enter the Password.

• Click Save

Nexus 2

• Enter the URL of your Nexus instance; this must end with /nexus/content.

• Enter the Username.

Nexus behind a reverse proxy

If your Nexus server is running behind a reverse proxy, for example, Nginx, the URL might not end with the default /repository for Nexus 3 or /nexus/content for Nexus 2, depending on what routes have been configured in the reverse proxy. If this is the case, ensure you use the URL configured in the reverse proxy.

Example: for Nexus 3, if http://nexus.company.io/repository is mapped to http://nexus.company.io/my-company/my-repository, use http://nexus.company.io/my-company/my-repository.

Example: for Nexus 2, if http://nexus.company.io/nexus/content is mapped to http://nexus.company.io/my-nexus-content, use http://nexus.company.io/my-nexus-content.

A green success message appears if Snyk can contact your repository.

If you see a yellow warning message, check your URL and credentials and try again.
