我有一个Spring Boot，带有一个父级和三个子级模块的spring data
jpa项目。我的模块之一负责我的JPA实体。我需要从此实体中使用liquibase生成一个xml变更日志。

在我的liquibase.properties中，我有以下代码：

changeLogFile=src/main/resources/db/changelog/db.changelog-master.xml
url=jdbc:mysql://localhost:3306/test
username=root
password=root
driver=com.mysql.jdbc.Driver
outputChangeLogFile=src/main/resources/db/outputChangeLog/liquibase-outputChangeLog.xml
referenceUrl=hibernate:spring:br.com.company.vacation.domain?dialect=org.hibernate.dialect.MySQLDialect
diffChangeLogFile=src/main/resources/liquibase-diff-changeLog.xml

因此，如果我尝试执行命令： liquibase：diff 我收到错误：

在我的pom.xml中，我像下面这样配置了liquibase：

<plugin>
    <groupId>org.liquibase</groupId>
    <artifactId>liquibase-maven-plugin</artifactId>
    <version>3.4.1</version>
    <configuration>
        <propertyFile>src/main/resources/liquibase.properties</propertyFile>
    </configuration>
        <dependencies>
            <dependency>
                <groupId>org.liquibase.ext</groupId>
                <artifactId>liquibase-hibernate4</artifactId>
                <version>3.5</version>
            </dependency>
            <dependency>
                <groupId>org.springframework</groupId>
                <artifactId>spring-beans</artifactId>
                <version>4.1.7.RELEASE</version>
            </dependency>
        </dependencies>
</plugin>

如果我执行 liquibase：generateChangeLog ，liquibase将从我现有的数据库中生成日志…但是，如果我尝试执行
liquibase：diff，则会 收到错误消息：

有人已经有这个问题了吗？
