对斯卡拉的卡斯巴来说不正确的JARs?
原标题:incorrect JARs for Casbah in Scala?
import com.mongodb.casbah.Imports._
val newObj = MongoDBObject( "abc" -> 1, "def" -> 2 )

这给了我以下错误:

有效 Date OrNummericTypeHolder 所需的类文件丢失。 包件 org 的引用值joda 指的是不存在的符号 。

我四处寻找解决这个错误,但失败了。请有人来指导我好吗?

我用 Scala 2.9.0 插件在Eclipse Java EE 中运行。在我的 Eclipse 项目中,我有以下参考图书馆。

2.9.0-1-2.1.5-1.jar.jar.

2.9.0-1-2.1.5-1.jar.jar.

2.9.0-1-2.1.5-1.jar.jar.

2.9.0-1-2.1.5-1.jar.jar.

2.9.0-1-2.1.5.0.jar.

mongo-1.0.jar

2.7.1.1.jar.(Mongo-java-driver-2.7.1.jar.)

2.9.0-0-1-0.2.0.0.jar.

后续问题:

在安托万指南解决了上述问题之后,我接着做了如下尝试:

newObj( "abc" )

并得到了此错误 :

无法兼容的 Class ChangeError: 类 com. mongodb. 基本目标不执行请求的接口 org.bson.BSONObject

知道怎么解决这个问题吗?

最佳回答

您可能需要在您的类路径中添加 < a href=> "http://joda-time. sourceforge.net/" rel=" no follow" >JodaTime 罐

问题回答

谢谢 安托万 你的指针很有帮助

我不得不加上以下的JARs, 才能使这项工作顺利进行:

秒4j-api-1.6.4.jar

jorda-time- 2.1. jar( jorda- time- 2. 1. jar)

Slf4j-spea- 1.6.4.jar. kgm

2.9.1-1.2. jar.
