Question

这是我的情景。

蟑螂DB Verions = 2.0
Flyway Ceriosn = 5.0.7
平台= Docker

我有一个使用flyway管理我的架构的java应用程序。

我的配置如下所示：我的flyway build.gradle看起来像：

buildscript {
dependencies {
    classpath "org.postgresql:postgresql:42.1.4"
 }
}
 plugins {
     id "org.flywaydb.flyway" version "5.0.7"
 }

description = "test-app"

flyway {
    url = jdbc:postgresql://localhost:26257/test_dev?sslmode=disable
 user = root
password = 
}

我在本地主机上以不安全模式运行蟑螂v 2.0。

当我跑步时：

gradle flywayClean

我得到了

Flyway upgrade recommended: CockroachDB 2.0 is newer than this version of Flyway and support 
has not been tested.
Unable to clean unknown schema: "test_dev"

当我跑步时：

gradle flywayMigrate

我得到：

Database: jdbc:postgresql://localhost:26257/test_dev (PostgreSQL 9.5)
Flyway upgrade recommended: CockroachDB 2.0 is newer than this version of Flyway and support has not been tested.

:test-migrations:flywayMigrate (Thread[Task worker for ':',5,main]) completed. Took 19.995 secs.

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':test-migrations:flywayMigrate'.
> Error occurred while executing flywayMigrate

  Unable to create schema "test_dev"

我可以在这里找到什么？

Answer 1

根据文档，仅支持版本1.1。

https://flywaydb.org/documentation/database/cockroachdb

Flyway 5.1版本将支持2.0版。

https://github.com/flyway/flyway/issues/1970

Answer 2

有同样的问题，所以我为那些有同样问题的人建造了它。使用它直到5.1版本，这是一个示例gradle文件的片段。

buildscript {
//...
  repositories {
    //...
      maven { url 'https://jitpack.io' }
    //...
  }
//..
}

plugins {
  //...
  id "com.radioafricagroup.plugins.flyway" version "0.6.7"
  //...
}

此处还有一篇中文帖子，解释了如果感兴趣我如何以及为什么这样做：https://medium.com/radio-africa-techblog/adventures-with-gradle-getting-flyway-to-work-with-cockroachdb-69aabf58cbd4

Flyway 5.0.7不与蟑螂db V. 2.0一起使用
