Pull request overview
Adds schema and backend secrets-conversion support for connecting to Matillion Data Productivity Cloud (DPC) alongside the existing Matillion ETL connection type.
Changes:
- Extend
MatillionConnectionto allow a newMatillionDPCauth config and introducelineageLookbackDays. - Add a new JSON schema defining the Matillion DPC authentication configuration (OAuth2 client credentials or PAT).
- Update the backend
MatillionConnectionClassConverterto convert/mask/unmask secrets for the new DPC auth type.

MatillionDPC auth config currently has an empty required list, which means an empty object (or one with only region) can pass schema validation. This will allow invalid connections to be saved and then fail later at runtime. Consider enforcing that either personalAccessToken is provided, or both clientId and clientSecret are provided (and ideally disallow providing both auth methods at once).

New schema fields (MatillionDPC auth option and lineageLookbackDays) aren’t covered by the existing configuration parsing tests for Matillion. Adding a unit test that parses a valid DPC config (PAT and/or client credentials) and asserts validation failures for missing credentials / out-of-range lineageLookbackDays would prevent regressions in schema-to-model generation and validation behavior.

The indentation in this multi-line tryToConvertOrFail(...) call doesn’t match the project’s standard Java formatting (and is likely to be rewritten by Spotless / google-java-format). Please reformat this block (e.g., by running mvn spotless:apply) so the continuation indentation is consistent and CI formatting checks don’t fail.

MatillionConnection does not declare any required fields (unlike most other pipeline connection schemas). With the new oneOf for connection, this means the top-level config can omit connection entirely and still validate, which is likely not a usable Matillion configuration. Consider adding a required list (at least connection, and possibly type if intended) to prevent silently-accepted invalid configs.
