Could not update Activiti database schema: unknown version from database: '5.20.0.1'

Question

I am getting a - Could not update Activiti database schema: unknown version from database: '5.20.0.1' ? Any idea why this error occurs ? I am using activiti-engine-5.18.0 jar

I am trying to deploy a process outside of Alfresco Activiti using eclipse.

Answer 1

Check wich version of activiti engine do you use in maven dependencies. Activiti 5.18.0 needs db version 5.18.0.0. Database version 5.20.0.1 is for Activiti engine 5.19.0.2.

Check version in your db table ACT_GE_PROPERTY and org.activiti.engine.ProcessEngine.VERSION. They need match.
