#7285 feat: CLI command `meltano lint` Issue created by aaronsteers MVP would be to simply print all JSON schema warnings that are emitted from the manifest file creation (

meltano compile

). Future iterations beyond initial MVP could: 1. Run test on all plugins (inline `meltano test --all`) 2. Warn on plugin config issues: 1. Non-existent lock files. 2. Missing

capabilities

declarations. 3. Unpinned pip URLs. 3. Warn on instances of deprecated or soon-to-be-deprecated features. 4. Warn if any required plugin config has been declared. 5. Warn if any provided config values do not match their setting's type, or their setting does not have a declared type, or their setting is not declared. 6. Warn if any settings defined as secrets are declared in yaml in clear text. 7. Run automatically after failure. Future iterations could also consider a

--fix

to resolve the subset of things that are auto-resolvable, such as: 1. Running

lock

on plugins that don't have lock files. 2. Applying simple yaml refactoring, as needed if future

meltano.yml

versions expect a different layout. Such as migrating from maps to lists. Depends on: • #6876, #7148 Cc @WillDaSilva, @tayloramurphy meltano/meltano
