Casbah MongoDB驱动程序编译器错误

我正在使用MongoDB的Casbah驱动程序，当我编译我的项目时，它失败了，出现以下错误：

[INFO] Compiling 12 source files to /core/target/classes at 1394903201140
[ERROR] error: bad symbolic reference. A signature in MongoClient.class refers to type MongoClientURI
[INFO] in package com.mongodb which is not available.
[INFO] It may be completely missing from the current classpath, or the version on
[INFO] the classpath might be incompatible with the version used when compiling MongoClient.class.
[ERROR] error: bad symbolic reference. A signature in MongoClient.class refers to type MongoClient
[INFO] in package com.mongodb which is not available.
[INFO] It may be completely missing from the current classpath, or the version on
[INFO] the classpath might be incompatible with the version used when compiling MongoClient.class.
[ERROR] two errors found

我将以下设置作为我的maven依赖项：

<dependency>
  <groupId>org.mongodb</groupId>
  <artifactId>casbah_2.10</artifactId>
  <version>2.7.0-RC2</version>
</dependency>

这与编译失败有关系吗？此外，我在调试模式下运行了maven，这是我在类路径中看到的：

我不明白其他依赖项，特别是像casbah-core_2.9.1、casbah-query_2.9.1这样的依赖项，是从哪里进入我的类路径的？我在pom.xml中没有将它们作为maven依赖项！这让人困惑。

我知道问题出在哪里了。我对salat框架有一个额外的依赖性，我不使用nut，这是在评估过程中添加的。它实际上是把那些额外的jar文件拉到类路径中，这实际上似乎是这个错误的原因

有卡斯巴论坛吗？我宁愿把我的问题贴在那里。这只是因为所有这些版本不兼容而变得恼火。
