DetectChangeType
Last updated: August 7, 2026
This check warns a user when a changeset includes a Change Type listed by the user as forbidden.
Uses
Property | Value |
Liquibase version required | 4.19.0+ |
Scope (--checks- | changelog |
Default status | enabled |
Default severity (exit code) | 0 ("INFO") |
Customizable settings | Yes (dynamic) |
Use the check to enhance deployment control of specific changesets by warning you if a forbidden Change Type is present. This way changesets do not violate policy by dropping tables or columns. This policy check, like other checks, can be configured with a severity level which returns an exit code designed to stop automated jobs, giving your team time to apply this Liquibase best practice.
Note: This check applies only to model-based changelogs such as XML, YAML, and JSON. It does not apply to SQL changelogs.
Before you begin
Ensure that the
--checks-scopeparameter includes the scope of this check.

Procedure
Enable
This check is enabled by default. To verify that it is currently enabled, run the checks show command:
liquibase checks show --check-name=<string>
Customize
This check is dynamic, meaning you can customize its settings. See the table on this page for more information.
1. Once you've enabled the check, follow the steps in the CLI to set new values.
Default values are shown in [brackets]. You can use these by pressing Enter. Alternatively, specify custom values. If a customization setting does not have a default value, you must specify custom values.
2. When finished, verify that your configuration is correct by running the checks show command.
liquibase checks show --check-name=<string>
3. If you need to make any other changes, run the checks customize command:
liquibase checks customize --check-name=<string>
Note: If you want to create another variant of this check with different settings, use the checks copy command to create a copy of the original check and then use the checks customize command to customize it.
Run
To run the check, use the checks run command.
