[RELATO]

Hi Michael

Please help

What I did?

git clone https://github.com/RedFroggy/angular-spring-hmac.git
cd angular-spring-hmac
mvn spring-boot:run

and the following error showed
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'liquibase' defined in class path resource [fr/redfroggy/hmac/configuration/DatabaseConfiguration.class]: Invocation of init method failed; nested exception is liquibase.exception.ChangeLogParseException: Error Reading Migration File: class path resource [liquibase/master.xml] cannot be resolved to URL because it does not exist
