【问题描述】：
我从https://www.playframework.com/download 下载了 Play Java Starter 示例
我需要使用 sqlite 数据库而不是内存中的 h2 数据库。我已经更改了application.conf 内部的必要行：
default.driver = org.sqlite.JDBC
default.url = "jdbc:sqlite:database.sqlite"
还将libraryDependencies += "org.xerial" % "sqlite-jdbc" % "3.8.11.2" 添加到build.sbt 中
当我尝试运行应用程序时，出现以下错误：
[info] application - Creating Pool for datasource 'default'
[info] p.a.d.HikariCPConnectionPool - datasource [default] bound to JNDI as DefaultDS
[info] p.a.d.DefaultDBApi - Database [default] connected at jdbc:sqlite:database.sqlite
[warn] o.h.e.j.s.SqlExceptionHelper - SQL Error: 1, SQLState: null
[error] o.h.e.j.s.SqlExceptionHelper - [SQLITE_ERROR] SQL error or missing database (no such table: information_schema.sequences)
[error] application -
接着是：

数据库文件database.sqlite自动创建在根文件夹内，0字节。
我错过了什么吗？
