The following snippet generates create / drop
sql for a particular database, whenever there is a modification to JPA entity classes.
How do I perform something equivalent of a 'for' operation where-in the following code can be used to generate
sql for all supported databases (e.g. H2, MySQL, Postgres)
Currently I have to modify db.groupId, db.artifactId, db.driver.version everytime to generate the
sql files
