我正在使用以下关于liquibase的快速入门
我的xml代码:
<?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"
xsi:schemaLocation="http://www.liquibase.org/xml/ns/dbchangelog
http://www.liquibase.org/xml/ns/dbchangelog/dbchangelog-2.0.xsd">
<changeSet id="1" author="bob">
<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>
当我使用“更新”命令通过命令行运行 Liquibase 时,Liquibase 告诉我这一点
INFO 8/31/12 9:17 AM:liquibase: Successfully released change log lock
Liquibase Update Failed: Content is not allowed in prolog.
SEVERE 8/31/12 9:17 AM:liquibase: Content is not allowed in prolog.

at liquibase.parser.core.xml.XMLChangeLogSAXParser.parse(XMLChangeLogSAXP
arser.java:106)
at liquibase.Liquibase.update(Liquibase.java:107)
我的更新命令是
liquibase --driver=com.mysql.jdbc.Driver --classpath=mysql-connector-java-5.1.6.jar --changeLogFile=database.xml --url="jdbc:mysql://localhost:3306/sample" --username=root --password=password update
我该怎么做呢?
