Wildfly cannot deploy the same project after upgrade from 27.0.0 Final to 30.0.1 Final.

Here's my actions to upgrade the Wildfly from 27.0.0 Final to 30.0.1 Final:

1. Upload and untar wildfly-30.0.1.Final.tar.gz to my server
2. Modify the standalone.xml in 30.0.1(datasource, deployment etc)
3. Start 30.0.1 by '/bin/sh /opt/jboss/default/bin/standalone.sh -b 0.0.0.0'

But the Wildfly 30.0.1 Final cannot start with the following error in server.log

 org.hibernate.service.spi.ServiceException: Unable to create requested service [org.hibernate.engine.jdbc.env.spi.JdbcEnvironment] due to: Unable to resolve name [org.hibernate.dialect.PostgreSQL9Dialect] as strategy [org.hibernate.dialect.Dialect]
