元数据表正在多次创建并且与Amazon Redshift数据库失败

Question

我正在使用具有flyway-gradle-plugin（3.2.1）的Gradle脚本（ver 2.3）将数据库更改部署到Amazon Redshift群集数据库中。

Flyway plugin: 'org.flywaydb:flyway-gradle-plugin:3.2.1' 
Driver jar:'RedshiftJDBC41-1.1.2.0002.jar' 
Driver class: 'com.amazon.redshift.jdbc41.Driver' 

现在的问题是（a）之后的元数据和（b）custome SQL脚本被执行是越来越创建的元数据表的两倍，即一次。执行（gradle clean build flywayMigrate --debug）后，只有“test_schema.test_tbl”表存在，但“test_schema.DB_SCHEMA_VER”不存在于Redshift数据库中。 请建议。

完整的堆栈跟踪如下：

Answer 1

我已经注意到这种情况发生红移/迁徙路线如果架构或表名称中包含混合大小写字符。

尝试配置一个全小写的元数据表名称，例如test_schema.db_schema_ver。
