Liquibase пытается создать одну и ту же таблицу дважды - PullRequest

/ 14 февраля 2019

Я новичок в liquibase и пытаюсь запустить какой-нибудь тест (версия 3.6.3).

  1. Я создал пустую базу данных с именем 'liquibase_testing'
  2. Я создал файл migrations.xml, который выглядит следующим образом:
    <?xml version="1.0" encoding="UTF-8"?>
    <databaseChangeLog xmlns="http://www.liquibase.org/xml/ns/dbchangelog"
                       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
                       xmlns:ext="http://www.liquibase.org/xml/ns/dbchangelog-ext"
                       xsi:schemaLocation="http://www.liquibase.org/xml/ns/dbchangelog http://www.liquibase.org/xml/ns/dbchangelog/dbchangelog-3.1.xsd
    http://www.liquibase.org/xml/ns/dbchangelog-ext http://www.liquibase.org/xml/ns/dbchangelog/dbchangelog-ext.xsd">
        <includeAll path="migrations" relativeToChangelogFile="true"/>
    </databaseChangeLog>
Я создал простой скрипт CREATE TABLE и сохранил его в каталоге migrations как 001-liquibase-testing-create-names-table.sql.Это выглядит так:
CREATE TABLE dbo.names (
name_id int identity,
first_name nvarchar(100),
last_name nvarchar(100),
primary key clustered (name_id)
)
Я запустил миграцию liquibase с помощью cli следующим образом:
    ./_liquibase/liquibase-3.6.3-bin/liquibase 
    --driver=com.microsoft.sqlserver.jdbc.SQLServerDriver 
    --classpath=./_jdbc/sqljdbc_7.2/enu/mssql-jdbc-7.2.0.jre8.jar      
    --changeLogFile=./liquibase_testing/resources/migrations.xml 
    --url="jdbc:sqlserver://myDbServer;database=liquibase_testing"      
    --username=liquibase_testing      
    --password=password     
    --logLevel=debug      
    migrate 

И я получаю эту ошибку:

    For more information, please use the --logLevel flag

Итак, таблица names создается, но затемпо какой-то причине Liquibase пытается создать его во второй раз и терпит неудачу.Я запустил трассировку профилировщика в базе данных и вижу 2 CREATE TABLE вызовов.
