问题
I'm completely new to Liquibase and I setup a rather simple project to become familiar with Liquibase. Unfortenately, I seem to fail at the very first steps which is very frustrating.
First my changelog.xml:
<?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">
<preConditions>
<dbms type="mysql"/>
</preConditions>
<changeSet id="1" author="maik">
<sql dbms="mysql" endDelimiter=";">
CREATE SCHEMA ods
</sql>
<createTable tableName="department">
<column name="id" type="int">
<constraints primaryKey="true" nullable="false"/>
</column>
<column name="name" type="varchar(50)">
<constraints nullable="false"/>
</column>
<column name="active" type="boolean" defaultValueBoolean="true"/>
</createTable>
</changeSet>
</databaseChangeLog>
Besides that, I have a liquibase.properties:
driver=com.mysql.jdbc.Driver
classpath=lib/mysql-connector-java-5.1.41-bin.jar
url=jdbc:mysql://localhost/prime
username=bla
password=bla
My pom.xml looks like this:
<?xml version="1.0" encoding="UTF-8"?>

When I run mvn package I get the following error:

For compliance with existing applications not using SSL the verifyServerCertificate property is set to 'false'. You need either to explicitly disable SSL by setting useSSL=false, or set useSSL=true and provide truststore for server certificate verification.

For me this seems like a problem with the schema, but I double-checked and cannot make out a problem. Most probably I am missing something very obvious here.
回答1:
Make sure to use the same version of liquibase-core and liquibase-maven plugin.
E.g. set version of liquibase-maven-plugin to <version>3.5.3</version>
