我正尝试使用以下参数运行liquibase(默认参数，仅修改路径)：

liquibase --driver=com.mysql.jdbc.Driver \

--classpath=mysql-connector-java-5.1.20-bin.jar

--changeLogFile=changelog.xml \

--url="jdbc:mysql://localhost/example" \

--username=root \

migratechangelog.xml非常小：

<?xml version="1.0" encoding="UTF-8"?>

xmlns="http://www.liquibase.org/xml/ns/dbchangelog"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xsi:schemaLocation="http://www.liquibase.org/xml/ns/dbchangelog

http://www.liquibase.org/xml/ns/dbchangelog/dbchangelog-2.0.xsd">

我得到的错误是：

不知道是什么原因造成的。我正在运行liquibase 2.0.5。

谢谢。
