当我尝试使用Liquibase 从数据库中删除所有对象时，它会收到错误。在调试模式下运行后，我发现它在删除表后尝试删除序列。因此得到错误'序列不存在'。 我在一个名为“1”的模式中运行，但在公共模式中，它成功构建（不尝试删除序列）。
这是我的ANT目标：
<target name="dropAll" depends="prepare" >
<dropAllDatabaseObjects
driver="${db.driver}"
url="${db.url}"
username="${db.username}"
password="${db.password}"
defaultSchemaName="${db.schema}"
promptOnNonLocalDatabase="yes"
classpathref="classpath"
/>
</target>
以下是日志错误：
[dropAllDatabaseObjects] Executing EXECUTE database command: DROP TABLE "1"."database_change_log" CASCADE
