I am trying to perform a rollback but I am getting the following error

The database URL has not been specified either as a parameter or in a properties file.´

I do have the database URL in my pom file as you can see below ,so I don't think that's the problem

The database has a password . Do I have to write it too? How can I fix this?

I'm not sure about the way of configuring Liquibase through pom.xml file. I think you could try this way:

  • instead of providing all database properties inside tag of pom.xml, create "liquibase.properties" and populate various properties relevant to liquibase(DB) in this file. For help with creating "liquibase.properties" file, visit this link

  • Try using configuration similar to below in your existing pom.xml file:


    <modelVersion>4.0.0</modelVersion>
        <groupId>com.my-group.app</groupId>
        <artifactId>Liqui<SampleDb>-app</artifactId>
        <version>1.0-SNAPSHOT</version>
        <build>
            <pluginManagement>
                <plugins>
                    <plugin>
                        <groupId>org.liquibase</groupId>
                        <artifactId>liquibase-maven-plugin</artifactId>
                        <version>3.9.0</version>
                        <configuration>
                            <propertyFile>liquibase.properties</propertyFile>
                        </configuration>
                        <dependencies>
                          <dependency>
                              <groupId><db_type></groupId>
                              <artifactId><db_type></artifactId>
                          </dependency>
                      </dependencies>
                    </plugin>
                </plugins>
            </pluginManagement>
        </build>
  • You could also try the following way by correcting your existing pom file. This link says to include liquibase attributes inside <configuration> section. May be try surrounding the liquibase attributes in your POM file in <configuration> section as below:
<configuration>
    <changeLogFile>changelog.xml</changeLogFile>
    <url>MyJDBCConnection</url>
    <username>dbuser</username>
    <password>dbpassword</password>
</configuration>

Yes, DB password is required for configuration

Cheers!!
