Maven dropAll

dropAll drops all database objects owned by the user. dropAll 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.

Uses

dropAll is typically used when there is a need to prepare an environment schema to be identical to another environment schema. dropAll 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.

dropAll should not be used in a production environment to prevent removal of required objects.

Maven configuration

You can configure Liquibase Maven in multiple ways. You can pass arguments like <changeLogFile> in Maven directly in your pom.xml file, in a liquibase.properties file referenced in your POM, as environment variables, or as JVM system properties.

Tip: For more information about the Maven configuration, see Configuring Maven.

Running the dropAll Maven goal

Running the dropAll goal requires a Maven project to be implemented.

To run the goal, type the following in your command prompt:

mvn liquibase:dropAll

When successful, the dropAll Maven goal produces the following output:
