它说谷歌云SQL驱动程序需要为flyway cli手动安装，但我如何手动安装它们？我在上面找不到任何文件。
编辑：我把它添加到我的飞行路线中。conf:flyway.jarDirs=/Users/my/flyway
然后我将驱动程序下载到该文件夹中：mvn dependency:get -Ddest=/Users/my/flyway -Dartifact=com.google.cloud.sql:postgres-socket-factory:1.3.0
但当我尝试使用它时，会出现以下错误：The SocketFactory class provided com.google.cloud.sql.postgres.SocketFactory could not be instantiated.
EDIT：这是针对我的DB 运行flyway baseline时的调试输出

这是为谷歌云上的Postgres准备的，是吗？
其目的是将驱动程序JAR放入Flyway产品内的drivers文件夹中(对于v4.0不能100%确定，因为它现在已经很老了——7.11是最新的(。jarDirs应该可以工作，但它是基于Java的迁移的理想场所。
但是，这看起来像是驱动程序中的一个问题。你是否确保将驱动程序的所有依赖项也放在那里？你能提供一个完整的调试日志(即flyway migrate -X(和异常详细信息吗？这样我们就可以看看了？
编辑：看看调试日志，这肯定是驱动程序中的一个问题——它无法实例化驱动程序内部的类。
