Grails 数据库迁移失败并出现 LiquibaseException

Question

我正在使用 Grails database migration plugin。

这是我的配置：

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

当我启动我的应用程序时，我得到了这个异常：

| 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

有什么想法吗？

问题是updateOnStartFileNames属性接受一个数组，而不是字符串，所以配置应该是

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

插件迭代这个列表依次执行每个，但是当给定一个字符串时，它迭代每个字符并执行它。然后 Liquibase 抛出异常，因为它无法识别第一个字母的后缀，在本例中为“c”。
