Liquibase中的liquibase.exception.DatabaseException

Question

在Liquibase中，每当我为大型数据库寻求generateChangeLog时，它都会给我错误，而对于小型数据库则运行正常。

我的错误控制台如下：

cmd命令：

   E:\liquibase-3.3.1-bin>liquibase 
   --driver=com.mysql.jdbc.Driver 
   --classpath=mysql-connector-java-5.1.6-bin.jar 
   --changeLogFile=xml\test11.xml 
   --url="jdbc:mysql://localhost:4928/test" 
   --username=root 
   --password=root 
   --diffTypes="tables,columns, foreignkeys,primarykeys, uniqueconstraints,
    data" generateChangeLog

错误：运行Liquibase发生意外错误：liquibase.exception.DatabaseException：java.lang.StringIndexOutOfBoundsException：字符串索引超出范围：-1

完整轨迹：

Answer 1

根据the comment of Sergei Visotsky，当存在数据库视图时，似乎会出现此异常。

就我而言，删除视图可以解决问题。
