Check liquibase changes

Create a profile in your maven project.

 <profile>
    <id>db-check</id>
    <build>
        <plugins>
            <plugin>
                <groupId>org.tkit.maven</groupId>
                <artifactId>tkit-liquibase-plugin</artifactId>

                <executions>
                    <execution>
                        <id>default</id>
                        <goals>

        </plugins>
    </build>
</profile>

After you run db-diff run maven command in the project directory:

mvn clean compile -Pdb-diff
mvn clean compile -Pdb-check
