Liquibase turns on output mode

problem description

I feel that there is so little information about Liquibase, basically about how to update it directly to the database. I don"t know how to implement its SQL Output mode. I just mentioned it on the official website, but I couldn"t find out where to set it for a long time.

the environmental background of the problems and what methods you have tried

it is now possible to update the database content directly through the gradle plug-in liquibase-gradle-plugin, but the goal is to generate a new sql file with its statements.

build.gradle

    liquibase {
        activities {
            dev {
                changeLogFile "${rootProject.projectDir}/db/liquibase/changelog-master.yaml"
                url "jdbc:MySQL://localhost:3306/windcoder?characterEncoding=utf8&useSSL=false"
                driver "com.mysql.jdbc.Driver"
                username "windcoder"
                password "root"
                outputFile "${rootProject.projectDir}/db/test.sql"
            }
            runList = "dev" //  
        }

    }

changelog-master.yaml

databaseChangeLog:
- changeSet:
      id: 1
      author: windcoder
      changes:
        - sqlFile:
            encoding: utf8
            path: db/mysql/test1.sql

test1.sql

INSERT INTO `sys_role` ( `name`, `remark`,display_order,created_date,last_modified_date,created_by, last_modified_by) VALUES ("", "",1,now(),now(),2,2);

what result do you expect? What is the error message actually seen?

expects to generate test.sql files, now executing gradle update can only save directly to the database.
