Grails數據庫遷移失敗，併發生LiquibaseException

Question

我正在使用Grails database migration plugin。

這是我的配置：

grails.plugin.databasemigration.updateOnStart = true 
grails.plugin.databasemigration.updateOnStartFileNames = 'changelog.groovy' 

當我開始我的應用程序我得到這個異常：

| Error 2013-08-20 08:55:47,356 [localhost-startStop-1] ERROR context.GrailsContextLoader - Error initializing the application: liquibase.exception.LiquibaseException: Cannot find parser that supports c

任何想法，爲什麼？

的問題是，updateOnStartFileNames屬性接受一個數組，而不是字符串，所以配置應該是

grails.plugin.databasemigration.updateOnStartFileNames = ['changelog.groovy'] 

在這個列表執行每個反過來插件迭代，但是當給定的字符串，遍歷每個角色並執行它。然後Liquibase拋出異常，因爲它不識別第一個字母的後綴，在這種情況下，'c'。
