Liquibase aggregator module for ZF2

Introduction

BaconLiquibase is an aggregator for Liquibase change sets. It will collect change sets from all your modules which supply them and create a master XML file, which you can then run through Liquibase as usual.

Usage

To use the module, add it to your application config. After that you must add a method called "getLiquibasePath()" in the "Module.php" of every module which supplies Liquibase updates. A simple example follows:

namespace AwesomeModule;

class Module
{
    public function getLiquibasePath()
    {
        return __DIR__ '/db/master.xml';
    }
}

As we are working with absolute paths here and Liquibase uses the full path to identify each change set, you have to tell it a logical file path within all of your change set files:

<databaseChangeLog
    …
    logicalFilePath="awesome-module/master.xml"
>
</databaseChangeLog>

In this case, we are making a filename up from the module name and the actual filename.

Aggregating all change sets

Before running Liquibase, you now have to create the aggregated file. To do this, simply make the following call:

php public/index.php bacon liquibase aggregate /path/to/output.xml
