The project sturcure is similar to any other projects, under the src folder you can find the database change logs partitioned by version:
$ ls src/main/groovy/com/kenshoo/liquibase/ 1 2 all_versions.groovy
In order to create a distributable package:
$ git submodule update --init $ gradle liquidPackage $ cd build/libs $ unzip liquid-distributable_2.zip
Note that the liquid-distributable zip version matches that of the schema version as stated in the build.gradle.
