Question

我正在使用带有flyway-gradle-plugin（3.2.1）的Gradle脚本（版本2.3）将数据库更改部署到Amazon Redshift Cluster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'

现在问题是元数据表被创建两次，即在（a）元数据和（b）custome sql脚本被执行之后再次创建。

执行（gradle clean build flywayMigrate --debug）后，只存在“test_schema.test_tbl”表，但Redshift数据库中不存在“test_schema.DB_SCHEMA_VER”。请建议。

完整的堆栈跟踪如下：

Answer 1

如果模式或表名包含大小写混合的字符，我注意到Redshift / Flyway会发生这种情况。

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

元数据表已多次创建，并且无法使用Amazon Redshift数据库
