exceção de tubo quebrado com MySql no aplicativo Grails

Então eu acredito que tudo menos dbCreate , url , username e password precisa estar em um bloco de propriedades:

dataSource {
    dbCreate = "update"
    url = "jdbc:mysql://urlofapp/myappname?useUnicode=yes&characterEncoding=UTF-8&autoReconnect=true"
    username = "root"
    password = "root"
    properties {
        minIdle = 5
        maxIdle = 25
        maxWait = 10000
        maxAge = 10 * 60000
        timeBetweenEvictionRunsMillis = 5000
        minEvictableIdleTimeMillis = 60000
        validationQuery = "SELECT 1"
        validationQueryTimeout = 3
        validationInterval = 15000
        testOnBorrow = true
        testWhileIdle = true
        testOnReturn = false
        jdbcInterceptors = "ConnectionState;StatementCache(max=200)"
        defaultTransactionIsolation = java.sql.Connection.TRANSACTION_READ_COMMITTED
    }
}
