Subject Error Migrating Ofbiz from derby to mysql
Date Thu, 20 Apr 2017 13:46:03 GMT
Hi community,


I have been using ofbiz 16.11 (latest release) with derby for quite some time. Few days ago
I started trying to migrate db from derby to mysql. I installed mysql 5.7 made the changes
in my.ini (I am on windows 10, though I tried same on *nix machines with same error). I also
created three dbs named ofbiz, ofbiztenant and ofbizolap and three users with same name and
same password.


For changes in entityengine.xml, I copy/pasted everything(mysql datasources and delegators)
from this guide<https://cwiki.apache.org/confluence/display/OFBIZ/How+to+migrate+OFBiz+from+Derby+to+MySQL+database>.
I have also put mysql-java-connector-6.0.6 in /framework/entity/lib/jdbc and added the same
as runtime dependency in build.gradle.


After doing all this when I run 'gradlew cleanAll loadDefault', I get the following errors

|E| The declared group name org.apache.ofbiz.olap has no corresponding group-map in entityengine.xml


and the following stacktrace
