Maven构建失败Liquibase： cvc-elt.1元素声明找不到

Question

我对Liquibase完全陌生，我设置了一个相当简单的项目来熟悉Liquibase。不幸的是，我似乎在第一步就失败了，这非常令人沮丧。

首先是我的变更日志。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>

除此之外，我还有一个酒鬼。特性：

driver=com.mysql.jdbc.Driver
classpath=lib/mysql-connector-java-5.1.41-bin.jar
url=jdbc:mysql://localhost/prime
username=bla
password=bla

我的pom。xml如下所示：

                </executions>
            </plugin>
        </plugins>
    </build>
</project>

当我运行mvn包我得到以下错误：

对我来说，这似乎是模式的问题，但我仔细检查了一下，无法找出问题。很可能我在这里错过了一些非常明显的东西。

确保使用相同版本的liquibase core和liquibase maven插件。例如，将liquibase maven插件的版本设置为
