I am new to Liquibase. I have already included maven plugins and liquibase to my pom.xml however when i update liquibase using mvn liquibase:update I get this error:
No plugin found for prefix 'liquibase' in the current project and in the plugin groups [org.apache.maven.plugins, org.codehaus.mojo] 
How can I fix this error so that when I type mvn liquibase:update it will run properly
Here are some of the dependencies that are in my pom.xml related to liquibase
