【问题描述】：
当我尝试编译我的项目时，我从 sbt 收到以下错误：

以下是我的build.sbt文件的内容：

以下是我的plugins.sbt文件的内容：
addSbtPlugin("com.earldouglas" %% "xsbt-web-plugin" % "0.9.0")
addSbtPlugin("com.eed3si9n" % "sbt-assembly" % "0.7.2")
addSbtPlugin("com.typesafe.sbteclipse" % "sbteclipse-plugin" % "2.5.0")
我生成了一个 Eclipse 项目，因为我可以查看 .classpath 文件。果然，我发现其中一些类不在classpath中……
如何将这些文件放入类路径？
感谢大家的帮助！
编辑：我决定在 ~/.ivy2/cache/org.eclipse.jetty. 中挖掘我的 JARS 我决定首先查找 SelectChannelConnector 类（我从 sbt 得到的第一个错误）。在org.eclipse.jetty 目录中有一个jetty-server 目录，所以我去了那里。现在在jetty-server 目录中有一堆 ivy xml 文件和两个目录，一个用于 jars，另一个用于 srcs。然后我进入 jars 目录。在 jars 目录中有 4 个 jars：
jetty-server-8.0.0.M3.jar jetty-server-9.0.0.M5.jar
jetty-server-8.1.8.v20121106.jar jetty-server-9.1.0.v20131115.jar
8.* 版本是由于我的build.sbt. 中的版本更改使用命令jar -tf [JAR-FILE]| grep nio' I found that theSelectChannelConnector.classfile exists in the8.jars and not the9.jars. Note that mybuild.sbt specifies the9.0.0.M5`罐子。
我的第一个想法是 sbt 只查看这些 9.* 罐子，如果我删除 8.* 罐子并重新加载我的项目，那么正确的类将被下载到 9.* 罐子中。事实并非如此。
目前我不确定还可以尝试什么。我可以尝试手动添加这些 jar，但这听起来不太好。
感谢大家的帮助！
