类型值plusHours不是org.joda.time.DateTime的成员 [英] Type value plusHours is not a member of org.joda.time.DateTime

问题描述

我正在使用Scala和Joda时间，但是我不能使用大多数方法.

I'm using Scala and Joda time, but I can't use most methods.

例如，这很好用

var now = DateTime.now()

但这不是

var now = DateTime.now()
var then = now.plusHours(2)

类型值plusHours不是org.joda.time.DateTime的成员

如果我建造，我还会收到以下错误:

If i build i receive also these errors:

加载DateTime时出错，缺少依赖项'org.joda.convert.FromString类'，C:\ Documents and Settings \ Vallo \ Mis documentos \ Downloads \ joda-time-2.2.jar(org/joda/time /DateTime.class)TP4未知Scala问题

error while loading DateTime, Missing dependency 'class org.joda.convert.FromString', required by C:\Documents and Settings\Vallo\Mis documentos\Downloads\joda-time-2.2.jar(org/joda/time/DateTime.class) TP4 Unknown Scala Problem

错误，缺少依赖项类org.joda.convert.ToString"，C:\ Documents and Settings \ Vallo \ Mis documentos \ Downloads \ joda-time-2.2.jar(org/joda/time /base/AbstractInstant.class)TP4未知Scala问题

error while loading AbstractInstant, Missing dependency 'class org.joda.convert.ToString', required by C:\Documents and Settings\Vallo\Mis documentos\Downloads\joda-time-2.2.jar(org/joda/time/base/AbstractInstant.class) TP4 Unknown Scala Problem

(文件C:\ Documents and Settings \ Vallo \ Mis documentos \ Downloads \ joda-time-2.2.jar存在)

(the file C:\Documents and Settings\Vallo\Mis documentos\Downloads\joda-time-2.2.jar exists)

但是，诸如DateTime.isBefore或.isAfter之类的方法可以正常工作.我感觉到静态方法是唯一对我有用的方法，但是我不确定.

However, methods like DateTime.isBefore or .isAfter works fine. I've got the feeling that static methods are the only one that work for me, but I'm not sure.

有任何线索吗?非常感谢.

Any clues? Thanks a lot.

推荐答案

似乎您可能需要添加

It seems that you might need to add joda-convert as a dependency too.
