斯卡拉 - 找到类型没有即时转换器：scala.Tuple5

我有一些代码行：斯卡拉 - 找到类型没有即时转换器：scala.Tuple5

import org.joda.time._ 
import org.joda.time.format._ 
val sampleDate = new DateTime(2015, 1, 1, 0, 0)

所以我得到一个错误：

我不知道为什么我得到这个错误，虽然这个网站： http://joda-time.sourceforge.net/api-release/org/joda/time/DateTime.html 我看到这个构造器是正确的....

DateTime 

public DateTime(int year, 
       int monthOfYear, 
       int dayOfMonth, 
       int hourOfDay, 
       int minuteOfHour) 
Constructs an instance from datetime field values using ISOChronology in the default time zone. 
Parameters: 
year - the year 
monthOfYear - the month of the year 
dayOfMonth - the day of the month 
hourOfDay - the hour of the day 
minuteOfHour - the minute of the hour 
Since: 
2.0

谢谢！

构造函数不是取6而是取5吗？ – LynxZh 2015-02-12 08:33:13

对不起，这是一个构造器日期时间公开日期时间（年整型， INT monthOfYear， INT请将dayOfMonth， INT HOUROFDAY， INT minuteOfHour） – 2015-02-12 08:55:01

看来，编译器治疗tuple5内的支架，你可以贴足代码段来查看是否有任何格式错误？ – LynxZh 2015-02-12 09:12:27

你的代码与2.7版本的乔达时间，但它不会与像1.6一些较旧的工作：

2.7: DateTime(int year, int monthOfYear, int dayOfMonth, int hourOfDay, int minuteOfHour) 
1.6: DateTime(int year, int monthOfYear, int dayOfMonth, int hourOfDay, int minuteOfHour, int secondOfMinute, int millisOfSecond)

的API被改变。

我REPL：

scala> val sampleDate = new DateTime(2015, 1, 1, 0, 0) 
warning: Class org.joda.convert.FromString not found - continuing with a stub. 
warning: Class org.joda.convert.ToString not found - continuing with a stub. 
warning: Class org.joda.convert.ToString not found - continuing with a stub. 
warning: Class org.joda.convert.FromString not found - continuing with a stub. 
warning: Class org.joda.convert.ToString not found - continuing with a stub. 
sampleDate: org.joda.time.DateTime = 2015-01-01T00:00:00.000+07:00

如果我尝试一些不恰当的参数：

scala> val sampleDate = new DateTime(2015, 1, 1, 0) 
java.lang.IllegalArgumentException: No instant converter found for type: scala.Tuple4

附：乔达时间罐被放置在lib_managed\jars文件夹内。所以你可以检查你的版本。我分别使用spark-1.2.0和joda-time-2.1.0，因此您应该至少使用Spark的1.2.0版本update来使用新的API。
