错误：groovy.lang.MissingMethodException：没有方法签名

Question

I have groovy util class as below:

package com.hypers.test.apitest.util

import groovy.sql.Sql

class DataBaseUtil {

    static def database

    static def connectDB(def url, def username, def password, def driver){
        database = Sql.newInstance(url,username,password,driver)
    }

    static def queryData(def sqlcommand){
        database.rows(sqlcommand)
    }

    static def queryData(def sqlcommand, def offset, def pageSize){
        database.rows(sqlcommand, offset, pageSize)
    }

    static def getFirstRow(def sqlcommand){
        database.firstRow(sqlcommand)
    }

    static def updateData(def sqlcommand){
        database.executeUpdate(sqlcommand)
    }

    static def insertData(def sqlcommand){
        database.executeInsert(sqlcommand)
    }

    static def deleteData(def sqlcommand){
        database.execute(sqlcommand)
    }

    static def closeDB(){
        database.close()
    }
}

I copied it to SoapUI for a reference, like:

package com.hypers.test.apitest.util

def JDBC_URL = context.expand( '${#Project#JDBC_URL}' )
def DB_UserName = context.expand( '${#Project#DB_UserName}' )
def DB_Password = context.expand( '${#Project#DB_Password}' )
def DB_Driver = context.expand( '${#Project#DB_Driver}' )

def sqlcommand = "SELECT id From configs_account Where name = 'APITEST_NewAccount_ValidData_ACTIVE'"

DataBaseUtil.connectDB(JDBC_URL, DB_UserName, DB_Password, DB_Driver)
DataBaseUtil.queryData(sqlcommand)
DataBaseUtil.getFirstRow(sqlcommand)

It works well with queryData method, but it's throws exception with getFirstRow method, I really can't figure out what's going on and get blocked for a very long time, please help to have a look, thanks.

Exception as below:

try

def database = DataBaseUtil.connectDB(JDBC_URL, DB_UserName, DB_Password, DB_Driver)
def rows = database.queryData(sqlcommand)
def row = database.getFirstRow(sqlcommand)
