Migrating to Google Cloud SQL using flyway, what j

问题:

I am trying to migrate my database(MySQL) dump file Google Cloud SQL using flyway commandline tool. I have copied google_sql.jar to flyway-commandline-1.6/jars/ and set the following properties in flyway-commandline-1.6/conf/flyway.properties:

flyway.driver=com.google.appengine.api.rdbms.AppEngineDriver
flyway.url=jdbc:google:rdbms://myinstancename/devdb
flyway.user=myusername
flyway.password=mypassword

However, this doesn't work and produces the following error:

FlywayException: Error instantiating database driver: com.google.appengine.api.rdbms.AppEngineDriver
Occured in com.googlecode.flyway.core.Flyway in method configure, line number 789
Caused by java.lang.ClassNotFoundException: com.google.appengine.api.rdbms.AppEngineDriver
Occured in java.net.URLClassLoader$1 in method run, line number 217

Could somebody help me in identifying the required jar files for flyway to work with Google Cloud SQL?

回答1:

It's weird and poorly documented on AppEngine's side, but you must also copy the MySQL Jdbc Driver into APPENGINE_HOME/lib/impl
