Using Liquibase DropAll Automagically 2

A while back gus posted about how to get liquibase to drop all on application start up. He had to jump through some hoops because dependsOn wasn't working properly. This seems to be OK now so I think the process can be simplified a bit...

Assuming the changelog is specified in grails-app/conf/liquibase/master.xml

resources.groovy

if (config.liquibase.on) {
   liquibaseDropAll(LiquibaseDropAll) { bean ->
      dataSource = dataSource
      changeLog = "classpath:liquibase/master.xml"
      bean.initMethod = 'init'
   }

   liquibase(SpringLiquibase) { bean ->
      dataSource = dataSource
      changeLog = "classpath:liquibase/master.xml"
      bean.dependsOn = ['liquibaseDropAll']
   }
}

LiquibaseDropAll.groovy

import liquibase.spring.SpringLiquibase
import org.codehaus.groovy.grails.commons.ConfigurationHolder

class LiquibaseDropAll extends SpringLiquibase {

   void init() {
      if (ConfigurationHolder.config.liquibase.dropAll) {
         super.createLiquibase(dataSource.connection).dropAll()
      }
   }

}




Disclaimer: I've only just started using it so it may still thow up some gotchas.
