Welcome to the forums @bbrouwer!
I work in product management at Liquibase. We have quite a few quality focused features in the works at Liquibase this year. The capabilities of Liquibase Linter line up nicely with what we have planned for a broader static analysis capability for Liquibase Changelogs, config files and generated SQL. If you’re open to it I’d love to chat with you directly about your experience with Linter and your efforts to build quality into your Liquibase usage. I have a public meeting scheduler that you can use to pick a time that works for us both.
We plan to evaluate several tools with integration potential while also assessing the need and cost of building something new. Until we have made those decisions I hesitate to integrate any one solution in a Liquibase managed extension. I really want to make sure the ultimate offering provides a friendly, unified experience across all of our quality controls. Maybe we can help you get the attention of the folks at the White Clark Group to move you forward?
Hope to talk with you soon!
