drop-all drops all database objects owned by the user.
drop-all will not drop functions, procedures, or packages for Liquibase Open Source. Functions, procedures, packages, and synonyms can only be dropped for Liquibase Pro supported objects.
drop-all is typically used when there is a need to prepare an environment schema to be identical to another environment schema.
drop-all is useful in the developer and test environments to remove unwanted objects to reset the database to "empty".
The command makes it easier to standardize another schema, compared to manually deleting the objects, or dropping and recreating the desired schema.
drop-all should not be used in a production environment to prevent removal of required objects.
To run the
drop-all command, specify the driver, classpath, and URL in the Liquibase properties file. For more information, see Create and Configure a liquibase.properties File. You can also specify these properties in your command line.
Then run the
drop-all global attributes
Tip: For best results, specify all commands and parameters in the
--kebab-case format in the CLI. If your preference is camelCase, it also works in the CLI.

Additionally, you need to be a Liquibase Hub user with a Liquibase Hub API Key set in one of the following ways:
Example Liquibase properties file
liquibase.hub.apiKey: <HubAPIKey> liquibase.hub.connectionId: <targetId> liquibase.hub.projectId: <projectId>
liquibase drop-all --hubProjectId=<projectId> --liquibaseHubApiKey=<addYourHubApiKeyHere> liquibase drop-all --hubConnectionId=<targetId> --liquibaseHubApiKey=<addYourHubApiKeyHere>
You can also set your properties as Liquibase environment variables:
LIQUIBASE_HUB_API_KEY="<HubAPIKey>" LIQUIBASE_COMMAND_HUB_PROJECT_ID="<projectId>" LIQUIBASE_COMMAND_HUB_CONNECTION_ID="<targetId>"
Note: To retrieve or manage your API keys, go to API Keys by selecting your account in the upper-right corner of the page. To find the
hubProjectId, select Projects > View Details. To find the
hubConnectionId, select Project > View Details > Targets > View Status > Target ID.
