I’m using the SchemaExport utility with needsJdbc=false to generate a SQL Schema. The hibernate-hikaricp JAR is on the classpath because im generating the schema during a Maven build, using the following Java code: final SchemaExport export = new SchemaExport(); export.doExecution(Action.CREATE, fa…
