Liferay table structure is modified in Service.xml, the tables in the database do not change

When booting Tomcat, console error:

Com.liferay.portal.OldServiceComponentException:Build namespace ievents have Build number 444 which is newer than 438.

This is because the Build.number is modified in the Service.properties file each time the service is build, and this number increases as the build service increases.

Therefore, modify the method to find the corresponding service.properties file, the Build.number will be changed a bit larger. Problem solving.

The Service.xml file is also executed to map the changes to the database.
