Liquibase maven diff没有表现出差异

我刚刚开始使用Liquibase，并希望使用maven插件来显示两个不同数据库之间的差异（我知道事实是不同的，因为我在其中一个中创建了一个名为'wallawalla'的随机表）但是Liquibase diff是显示没有结果 .

这是我的pom.xml：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
        <modelVersion>4.0.0</modelVersion>
        <groupId>com.me</groupId>
        <artifactId>databasechecker</artifactId>
        <version>0.0.1-SNAPSHOT</version>


        <build>
            <plugins>
                <plugin>
                    <groupId>org.liquibase</groupId>
                    <artifactId>liquibase-maven-plugin</artifactId>
                    <version>3.2.2</version>
                    <configuration>
                        <propertyFile>liquibase.properties</propertyFile>
                    </configuration>

                    <dependencies>
                        <dependency>
                            <groupId>org.liquibase.ext</groupId>
                            <artifactId>liquibase-hibernate3</artifactId>
                            <version>3.4</version>
                        </dependency>
                        <dependency>
                            <groupId>org.liquibase</groupId>
                            <artifactId>liquibase-core</artifactId>
                            <version>3.2.2</version>
                        </dependency>
                    </dependencies>
                </plugin>
            </plugins>
        </build>
    </project>

这是我的liquibase.properties：

changeLogFile=changelog-master.xml

    url=jdbc:oracle:thin:@xxxxxx.com:1521:ORCL
    driver=oracle.jdbc.driver.OracleDriver
    username=synch_dev
    password=xxxxxx


    referenceUrl=jdbc:mysql://localhost:3306/test
    referenceDriver=com.mysql.jdbc.Driver
    referenceUsername=root
    referencePassword=xxxxxx

然后我跑：

c:\Dev\eclipseworkspace\databasechecker>mvn liquibase:diff

但它没有显示变化：

    Reference Database: root@localhost @ jdbc:mysql://localhost:3306/test (Default Schema: test)

任何想法我怎么能得到它来展示我的差异？

EDIT

当我在命令行上使用liquibase.bat直接调用liquibase时，差异工作正常，liquibase.properties文件中的属性作为参数传递给命令 . 那么它是maven插件的错误，还是我错误地配置了它？
