How to Apply Your Liquibase Pro License Key

Include the Liquibase Pro license key in the Liquibase properties file and save it. For example:

liquibase.licenseKey: aei76ou32thp785463214

Pass the Liquibase Pro license key as a parameter in the command line during runtime:

liquibase --license-key=[paste the Liquibase Pro license key] [command]

For example:

liquibase --license-key=aei76ou32thp785463214 update

Set the Liquibase Pro license key as an environment variable in the command line.

On Windows:

set LIQUIBASE_LICENSE_KEY=aei76ou32thp785463214

On Linux/macOS:

export LIQUIBASE_LICENSE_KEY=aei76ou32thp785463214

Set the Liquibase Pro license key with the JAVA_OPTS Environment Variable in the command line:

JAVA_OPTS="Dliquibase.licenseKey=<enter license key here>"

Pass the Liquibase Pro license key while using a Docker container. Docker allows the use of --env in the command.

docker run --env LIQUIBASE_LICENSE_KEY=<enter license key here>...  \
-it liquibase/liquibase:latest sh

If you use Maven, include the Liquibase Pro license key in the <properties> section of your pom.xml file:

<liquibaseLicenseKey>key-goes-here</liquibaseLicenseKey/>

For example:

<plugin>
    <groupId>org.liquibase</groupId>
    <artifactId>liquibase-maven-plugin</artifactId>
    <version>0-SNAPSHOT</version>
    <configuration>
        <changelogFile>com/example/changelog_v4.6.xml</changelogFile>
        <liquibaseLicenseKey>key-goes-here</liquibaseLicenseKey>
    </configuration>
</plugin>

Note: In older versions of Liquibase, you must use the syntax <liquibaseProLicenseKey> instead of <liquibaseLicenseKey>.

If you use Azure DevOps and pass your license key as an environment variable, you can set the value of LIQUIBASE_LICENSE_KEY in your Azure DevOps pipeline setting file:

script: |
    echo "Running Policy Checks"
    liquibase checks run --changeLogFile=mysqlChangelog.xml
displayName: 'Run Policy Checks'
env:
    LIQUIBASE_LICENSE_KEY: $(LiquibaseKey)

In this example, LiquibaseKey is the name of the Azure DevOps project variable whose value is the license key.

You can directly embed your Liquibase Pro license key (myProLicenseKey) in a custom Java application by following these steps:

1. In your Maven pom.xml file, point to liquibase-commercial.jar as a dependency:

<dependency>
    <groupId>org.liquibase</groupId>
    <artifactId>liquibase-commercial</artifactId>
    <version>4.30.0</version>
</dependency>

2. In your custom Java file, import the following:

import com.datical.liquibase.ext.config.LiquibaseLabsConfiguration;

3. In your custom Java file, call on the LiquibaseLabsConfiguration class. For example, to specify your license key so that you can run the Liquibase Pro update-one-changeset command:

Scope.child(LiquibaseLabsConfiguration.LICENSE_KEY.getKey(), "myProLicenseKey", () ->
    new CommandScope(UpdateOneChangeSetSqlCommandStep.COMMAND_NAME)
        .addArgumentValue(DbUrlConnectionArgumentsCommandStep.DATABASE_ARG, liquibase.getDatabase())
        .addArgumentValue(DatabaseChangelogCommandStep.CHANGELOG_FILE_ARG, "/db_schema/changelog.xml")
        .addArgumentValue(UpdateOneChangeSetCommandStep.CHANGESET_AUTHOR_ARG, "fl")
        .addArgumentValue(UpdateOneChangeSetCommandStep.CHANGESET_ID_ARG, "1")
        .addArgumentValue(UpdateOneChangeSetCommandStep.CHANGESET_PATH_ARG, "/db_schema/changelog.xml")
        .execute()
);
