liquibase is not able execute change-set in DB using its api

I am trying to integrate liquibase with my project. but i am not able to exceute change log using Liquibase java API.

I could not figured out why non of the change-set is getting executed and reflected in DB.

In summary no change-sets has been executed and my DB has no Tables (except DATABASCHANGELOG and DATABASECHANGELOGLOCK ) in it.

 could not post all detail here. so i have posted stackoverflow  question. Please refer below link:


did i missed to initialize any api method? due to this i stuck in integration.
