【中文标题】FlyWay 迁移脚本【英文标题】：FlyWay migrate scripts 【发布时间】：2018-02-28 11:55:44 【问题描述】：你能帮忙解释为什么flyway不能安装脚本吗 ?
我的架构是空的，只有一个创建 flyway 的表。但它也是空的。
如何正确配置 FlyWay？我的脚本有以下形式

【问题讨论】：
需要更多信息。 什么不工作？这些日志声明表明 Flyway 认为不需要迁移。18:43:30,945 INFO [stdout] (ServerService Thread Pool -- 14) 2017-09-19 18:43:30 INFO DbMigrate:44 - Schema "TEST_SERVER" is up to date. No migration necessary.
我添加了一些信息
@BobKuhar 有两个脚本没有执行。该方案完全是空的。
【参考方案1】：
Flyway 找不到您的迁移文件，因此它认为一切都是最新的：
INFO DbValidate:44 - Successfully validated 0 migrations (execution time 00:00.018s)
您需要指定一个位置或将您的迁移移动到它已经在搜索的位置。使用setLocations() 这样做。
【讨论】：
【参考方案2】：如果您使用 maven 构建此 jar - flyway-1.0-SNAPSHOT.jar，请确保 src/main/resources 有一个包含您的 V1__20170918_Initial_structure.sql 的 db/migration 文件夹
如果它能够解决您的问题，请告诉我。
