斯卡拉 - 找到類型沒有即時轉換器：scala.Tuple5

我有一些代碼行：斯卡拉 - 找到類型沒有即時轉換器：scala.Tuple5

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

所以我得到一個錯誤：

我不知道爲什麼我得到這個錯誤，雖然這個網站： http://joda-time.sourceforge.net/api-release/org/joda/time/DateTime.html 我看到這個構造器是正確的....

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

謝謝！

構造函數不是取6而是取5嗎？ – LynxZh 2015-02-12 08:33:13

對不起，這是一個構造器日期時間公開日期時間（年整型， INT monthOfYear， INT請將dayOfMonth， INT HOUROFDAY， INT minuteOfHour） – 2015-02-12 08:55:01

看來，編譯器治療tuple5內的支架，你可以貼足代碼段來查看是否有任何格式錯誤？ – LynxZh 2015-02-12 09:12:27

你的代碼與2.7版本的喬達時間，但它不會與像1.6一些較舊的工作：

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被改變。

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

如果我嘗試一些不恰當的參數：

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

附：喬達時間罐被放置在lib_managed\jars文件夾內。所以你可以檢查你的版本。我分別使用spark-1.2.0和joda-time-2.1.0，因此您應該至少使用Spark的1.2.0版本update來使用新的API。
