部署到AWS的Grails应用程序在初始化时引发异常

我最近尝试将我的Grails应用程序部署到Amazon Web服务（Elastic Beanstalk），但失败了。我相信我与亚马逊RDS的连接是正确的。你可以在下面看到我的配置。有趣的是，当我在虚拟服务器上的EclipseIDE中构建这个项目时，没有任何错误，它连接到AWS的数据库也很好

environments {
    production {
        dataSource {
            pooled = true
            username = "user"
            password = "pass"
            pooled = true
            dbCreate = "update"
            driverClassName = "com.mysql.jdbc.Driver"
            url = "jdbc:mysql://URLTOAWS/SCHEMENAME"
            properties {
                validationQuery = "SELECT 1"
                testOnBorrow = true
                testOnReturn = true
                testWhileIdle = true
                timeBetweenEvictionRunsMillis = 1800000
                numTestsPerEvictionRun = 3
                minEvictableIdleTimeMillis = 1800000
            }
        }
    }

这可能提供了一个巨大的线索。这是堆栈跟踪
