Uses

The dropAll goal is typically used when there is a need to prepare an environment schema to be identical to another environment schema. The dropAll goal is useful in the developer and test environments to remove unwanted objects to reset the database to empty.

The command makes standardizing another schema easier than manually deleting the objects or dropping and recreating the desired schema.

The dropAll The goal should not be used in a production environment to prevent the 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. To learn about each file's syntax, see Maven 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

Maven dropAll output

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