Spring Boot 4.0.6 bumps the managed `mongodb.version` from 5.6.4 to 5.6.5. Our `dependencies.gradle` still pinned 5.6.4, which lost to Spring Boot's 5.6.5 during transitive resolution and tripped the `validateDependencyVersions` task across every grails-data-mongodb module and mongodb test example (bson, mongodb-driver-core, mongodb-driver-sync, bson-record-codec). Bump the explicit pin to 5.6.5 so our BOM matches what Spring Boot 4.0.6 manages and the validator sees a single source of truth. Assisted-by: claude-code:claude-opus-4-7
Spring Boot 4.0.6 bumps `tools.jackson:jackson-bom` from 3.1.0 to 3.1.2, but `io.micronaut.platform:micronaut-platform:5.0.0-M2` still pins 3.1.0. With both platforms imported into grails-micronaut-bom, the probe in `validateDependencyVersions` sees Micronaut's 3.1.0 while actual resolution in consuming projects picks Spring Boot's 3.1.2 - flagging `grails-test-examples-micronaut` as a version mismatch. Apply the same exclusion pattern already used for Groovy and Spock: exclude `tools.jackson` from the Micronaut platform import so spring-boot-dependencies is the single source of truth for Jackson 3, mirroring how SB owns Groovy/Spock in grails-base-bom. The probe and project resolution now agree on 3.1.2, and consumers stay aligned with the Jackson version Spring Boot tests against. Assisted-by: claude-code:claude-opus-4-7

Pull request overview
Updates Grails’ dependency management to align with Spring Boot 4.0.6 and resolves BOM drift conflicts detected by validateDependencyVersions, ensuring consistent transitive resolution across Grails and Micronaut BOM imports.
Changes:
- Bump
spring-boot.versionfrom4.0.5to4.0.6independencies.gradle. - Bump pinned MongoDB driver version from
5.6.4to5.6.5to match Spring Boot 4.0.6. - Exclude
tools.jacksonfrom the Micronaut platform import ingrails-micronaut-bomso Spring Boot remains the single source of truth for Jackson 3.

Micronaut released 5.0.0 https://github.com/micronaut-projects/micronaut-platform/releases shouldn't we update?
| // Exclude Spock since the base BOM manages that version. | ||
| // Exclude Jackson 3 (tools.jackson) since spring-boot-dependencies manages that version, | ||
| // and Micronaut can lag behind Spring Boot's patch bumps (e.g. SB 4.0.6 ships | ||
| // jackson-bom 3.1.2 while micronaut-platform 5.0.0-M2 still pins 3.1.0). |

Why not bump to 3.1.2 in micronaut bom?

Dependency-version fallout (a.k.a. why this PR has three commits)
The
validateDependencyVersionsCI job caught two transitive-version conflicts introduced by the SB 4.0.5 → 4.0.6 bump. Both are upstream BOM drift, not anything broken in our build - but our pins (and the Micronaut platform's pins) had to be reconciled so the validator sees a single source of truth.1. MongoDB driver 5.6.4 → 5.6.5
Spring Boot 4.0.6 bumps its managed
mongodb.versionfrom 5.6.4 to 5.6.5. Ourdependencies.gradlewas still pinning 5.6.4, so the higher SB version won during transitive resolution and the validator flagged every grails-data-mongodb module and mongodb test example:Affected projects:
grails-data-mongodb,-bson,-core,-ext,-spring-boot,-gson-templates,-docs, plus thegrails-test-examples-mongodb-*set.Fix: Bump
mongodb.versionto5.6.5independencies.gradleso our pin matches what Spring Boot 4.0.6 manages.2. Jackson 3 BOM: SB 4.0.6 ships 3.1.2, Micronaut platform still pins 3.1.0
Spring Boot 4.0.6 also bumps
tools.jackson:jackson-bomfrom 3.1.0 to 3.1.2.io.micronaut.platform:micronaut-platform:5.0.0-M2has not caught up yet and still pins 3.1.0.
