Dear Sir, Pls. help I am starting wildfly with ./standalone.sh --server-config=standalone-full.xml It works without errors. I cloned latest aerogear-unifiedpush-server and installed with maven I follow the steps in https://aerogear.org/docs/unifiedpush/ups_userguide/ index/#server-installation. I am using postgres database. It is running on localhost and the port is 5432. postgres connector version is postgresql-9.4.1207.jar. I created all databases. Generated the UnifiedPush Database and Datasource. liquibase.properties contains the following info url=jdbc:postgresql://localhost:5432/unifiedpush driver=org.postgresql.Driver username=unifiedpush password=unifiedpush changeLogFile=liquibase/master.xml *ON STEP 'CREATE THE DATABASE SCHEMA'* I run ./bin/ups-migrator update I get the error 'Unexpected error running Liquibase: Precondition error' Regards, Sonu Kumar Gupta _______________________________________________ Aerogear-users mailing list Aerogear-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/aerogear-users
