We just need following during SchemaExport:

// We just want to create a ddl.sql file to setup the SchemaImporter
// for dynamically added dataSources
boolean stdout = false
boolean exportToDatabase = false
boolean justDrop = false
boolean justCreate = true
schemaExport.execute(stdout, exportToDatabase, justDrop, justCreate)
