當我使用可重複的遷移時,我觀察到一些奇怪的Flyway行爲。文檔指出:Flyway可重複遷移 - 在版本化之前執行?
在單次遷移運行中,在執行完所有待執行的版本化遷移後,始終應用可重複遷移。
但在我看來,似乎可重複的遷移(這是重新創建一個數據庫視圖)失敗,因爲它是在版本遷移之前執行的。

難道我做錯了什麼?
我使用飛路-行家-插件4.0.1(也測試了4.0)具有以下屬性:
Maven:
<cleanDisabled>true</cleanDisabled>
<outOfOrder>true</outOfOrder>
<table>schema_version</table>
<repeatableSqlMigrationPrefix>R</repeatableSqlMigrationPrefix>
<sqlMigrationPrefix>V</sqlMigrationPrefix>
Config file:
flyway.user=flyway
flyway.password=█
flyway.url=jdbc:sqlserver://█;databasename=█
flyway.locations=filesystem:flyway/upgrade/█`
// EDIT1:
- 當outOfOrder設置爲假遷移仍然失敗,
- 乾淨+遷移似乎工作,但是這並不能解決問題,
- 我注意到了一件事 - 當我將數據庫回滾到版本201605041 43800000列表(浮動信息)末尾顯示可重複的遷移,但當20160504145200000遷移突然成功執行時,它們處於中間(如上表所示)。我不確定,如果這與實際的執行順序有任何關係。
謝謝,我已經更新了OP。 –
