Yes.

Create an extra feature to add json-schema-validation module to the test class path.

@sdelamo What kind of logic do you want for adding one and/or the other, or validating the presence of them?

• [x] add json-schema-validator feature if not present when selecting json-schema feature?
• [x] FeatureValidator to assert json-schema is present if json-schema-validator is selected?
• [ ] something else?

Edit: I did what's checked. Can make changes if desired.

CI is failing on :test-features:test because ThymeleafSpec generates a project with views-fieldset-tck, and the TCK test fails. I'll see if I can figure it out.

Edit: see #2435

ping @sdelamo I merged the ThymeleafSpec fix and CI is green now. This should be GTG.

Let's wait until we have a release of Micronaut JSON Schema.
