Dependency convergence failed: nimbus-jose-jwt

[matsev]

Dependency convergence conflict for com.nimbusds:nimbus-jose-jwt using Spring Boot version 3.1.3 / Spring Security version 6.1.3

Step by step:

1. Copy the following pom.xml file:

                </executions>
            </plugin>
        </plugins>
    </build>
</project>

2. Execute mvn validate

Expected result
The dependencies should converge, i.e. every (transitive) dependency should have exactly one version specified.

Actual result
Two different versions of the nimbus-jose-jwt are imported transitively:

Probably related to #13333

There's an additional problem here with micrometer-observation that Boot's dependency management addresses. I think that's a reasonable role for Boot to play as the problem is across multiple projects (Spring Framework and Spring Security). The problem with nimbus-jose-jwt is different as it's two modules within the same project that cannot agree upon the version of a transitive dependency.

Thanks for reporting this @matsev, and thanks for the additional info @wilkinsona.

I opened gh-13333 for this, but wasn't clear on what happened to get us to this point. With some research, I now see what happened. Our dependency management updates are designed to keep the version of oauth2-oidc-sdk and nimbus-jose-jwt versioned together for consistency, which is challenging due to that project's particular versioning scheme.

When we updated to com.nimbusds:oauth2-oidc-sdk version 9.43.2, it updated nimbus-jose-jwt to the version that library depends on, which is com.nimbusds:nimbus-jose-jwt:9.31.

However, in the very next release of com.nimbusds:oauth2-oidc-sdk, which is 9.43.3, they downgraded (went back) to com.nimbusds:nimbus-jose-jwt:9.24.4.

So I believe we need to simply apply the same downgrade ourselves. Anything you folks see that I'm missing?

@sjohnr I am sorry, I don't have much to add to this issue. I was just surprised when I discovered the conflicting versions after we added Spring Boot Oauth2 Starter as a dependency to our project. We do not plan to implement any Oauth2 logic ourselves so we are happy as long as the Oauth2 abstractions provided by Spring Boot / Spring Security works as expected.

That said, perhaps there is a better way? Questions:

• Is com.nimbusds providing a Maven bom file (I guess not, since this issue surfaced)?
• Maybe connect2id has a compatibility matrix for their products (I looked at the nimbus-oauth-openid-connect-sdk and the nimbus-jose-jwt product pages, but there was none)?
• Perhaps you can reach out to support@connect2id.com and ask for advice (I found this email address at the bottom of the readme at the oauth2-oidc-sdk repository? There is also a page with issue tracking, maybe one can submit new tickets there if one signs up?
• Also noticing that the oauth2-oidc-sdk project has released two more major versions (10.x and 11.x), would it be feasible to upgrade (or perhaps that would cause breaking changes to spring-security-oauth2-client, prompting for a major version bump of it as well)?
• The nimbus-jose-jwt package on the other hand has only minor version updates, the 9.35 being the latest one, maybe that solves the problem?

[sjohnr]

I've opened an issue on the connect2id issue tracker.

Another question:
Would it make any sense for Spring Security's build pipeline to have something like the Maven dependency plugin's DependencyConvergence rule in order to discover these kinds of issues before a release? 😄

I'm no Gradle expert, but it seems like there's an available alternative for Gradle too.
