Grails数据库迁移因LiquibaseException而失败

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，我得到了这个例外：

| 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

任何想法为什么？

问题是updateOnStartFileNames属性采用数组而不是字符串，因此配置应为

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

插件迭代遍历此列表，依次执行每个列表，但是当给定一个String时，它会迭代每个字符并执行它。 Liquibase然后抛出异常，因为它不识别第一个字母的后缀，在这种情况下，'c'。
