当我尝试编译项目时，我从sbt得到以下错误：

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类路径中......
如何将这些文件放入类路径？
感谢您的帮助！
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获得的第一个错误）。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目录中有一堆常春藤xml文件和两个目录，一个用于jar，另一个用于srcs。然后我进入了jars目录。在jars目录中有4个罐子：
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.*版本归因于我的build.sbt.中的版本更改使用了命令jar -tf [JAR-FILE]| grep nio' I found that the SelectChannelConnector.class file exists in the 8. jars and not the 9。 jars. Note that my build.sbt specifies the 9.0.0.M5` jar。
我的第一个想法是，sbt只关注这些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{{1罐子。事实并非如此。
我不确定此时还有什么可以尝试的。我可以尝试手动添加这些罐子，但这听起来不错。
感谢您的帮助！

我认为这已经解决了here
基本上，您将jetty-webapp标记为container和provided
"org.eclipse.jetty" % "jetty-webapp" % "8.1.7.v20120910" % "container;provided"
希望它有所帮助。

您将码头标记为“已提供”。这意味着jetty在运行时不可用。
