jdbi: POM Dependency Conflict

Greetings!

I’m opening an issue instead of a PR to get a consensus on what the fix should be (at which point I will submit a PR).

The issue is that when trying to build DropWizard against 3.3.0, the build fails:

https://github.com/dropwizard/dropwizard/pull/2394

The reason for the failure is that jdbi3-core is pulling in both antlr-runtime 3.3 and 3.4. This issue did not exist in 3.2.1.

This problem was introduced by depending on stringtemplate 4.0.2:

https://repo.maven.apache.org/maven2/org/antlr/stringtemplate/4.0.2/stringtemplate-4.0.2.pom

As you can see this explicitly requires antlr-runtime 3.3.

Proposals

1. Rollback the dependency update for string template.
2. Exclude antlr runtime from the string template dependency definition.

Please let me know which you prefer and I will make it happen.

NOTE: Regardless of the above, I would like to add dependency convergence enforcement to your build to catch this sort of issue going forward.

EDIT: JDBI3 correctly fails its build with enforcement enabled:

[WARNING] Rule 0: org.apache.maven.plugins.enforcer.DependencyConvergence failed with message:
Failed while enforcing releasability the error(s) are [
Dependency convergence error for org.antlr:antlr-runtime:3.4 paths to dependency are:

and
+-org.jdbi:jdbi3-core:3.3.0
  +-org.antlr:antlr-runtime:3.4
    +-org.antlr:antlr-runtime:3.3

EDIT2: What’s interesting, is forcing the inclusion of string template in core results in the following failures:

[WARNING] Rule 0: org.apache.maven.plugins.enforcer.DependencyConvergence failed with message:
