Maven dropall

dropAll drops all database objects owned by the user. dropAll will not drop functions, procedures, or packages for the community version of Liquibase. Functions, procedures, and packages 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

Liquibase Maven can be configured multiple ways. One way is to define your Liquibase configuration properties in your pom.xml file. You can also indicate the location of your liquibase.properties file using the following syntax:

<liquibase.propertyFile>path/to/properties_file</liquibase.propertyFile>

Note: Replace path/to/properties_file with the location of your default properties file. See the example below.

<liquibase.propertyFile>${project.basedir}/local.liquibase.properties</liquibase.propertyFile>

Multiple profiles can be created in the pom.xml which contain different Liquibase properties. See the example below.

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
