Question

我正在使用数据库迁移：2.0.0.RC1和Grails 3.0.7。我遇到了让迁移运行的问题。当我启动时，我收到以下错误：

问题似乎是找不到changelog.groovy文件。我在GroovyChangeLogParser内调试，它在这一行失败：

inputStream = StreamUtil.singleInputStream(physicalChangeLogLocation, resourceAccessor)

如果我检查resourceAccessor，它没有grails-app / migrations文件夹，因此无法找到changelog.groovy文件。我不知道从哪里开始。我错过了一些配置吗？我有这个插件在Grails 2.3.7项目中正常工作。

似乎你错过了自述文件中提到的gradle配置：

sourceSets {
    main {
        resources {
            srcDir 'grails-app/migrations'
        }
    }
}
