Question

我想使用liquibase标签功能。首先，我将以下命令运行到cmd（使用liquibase.properties设置等）

liquibase --changeLogFile=changeLog.xml update

其中changeLog.xml包含如下：

<?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-3.1.xsd">

    <changeSet id="1" author="ivan">
        <createTable tableName="customer">
            <column name="id" type="varchar2(42)" />
            <column name="name" type="varchar2(42)" />
        </createTable>
    </changeSet>
</databaseChangeLog>

并且没有错误发生。

现在，我想使用以下命令标记当前数据库状态：

liquibase --changeLogFile=changeLog.xml tag exampletag

我也尝试使用以下命令

liquibase tag exampletag

唉，两次尝试都失败并出现相同的错误消息，如下所示

Unexpected error running Liquibase: Unknown Reason

如何通过命令行传递命令来正确标记当前状态的数据库？谢谢！

更新

这是我从运行第一个命令获得的堆栈跟踪。而且，我正在使用Liquibase 3.2.0

此错误已在Liquibase 3.2.1中修复。

使用liquibase时在命令行中使用标记时出错
