当我尝试跳船时，它向我大吼大叫，大概是这样的：
2018-12-08 16:14:29.214:WARN:oeja.AnnotationParser:qtp1854731462-11: org.eclipse.jetty.util.thread.strategy.ProduceExecuteConsume scanned from multiple locations: [jar:file:///Users/me/Documents/Projects/myproject/target/webapp/WEB-INF/lib/jetty-util-9.4.8.v20171121.jar!/org/eclipse/jetty/util/thread/strategy/ProduceExecuteConsume.class, jar:file:///Users/me/.ivy2/cache/org.eclipse.jetty/jetty-runner/jars/jetty-runner-9.4.8.v20171121.jar!/org/eclipse/jetty/util/thread/strategy/ProduceExecuteConsume.class]
和更多类似的东西。看来Ivy缓存的jar文件与本地版本冲突。
这是我的SBT构建依赖项：
resolvers += Classpaths.typesafeReleases
libraryDependencies += "org.scalacheck" %% "scalacheck" % "1.14.0" % "test"
libraryDependencies += "org.scalatest" % "scalatest_2.12" % "3.0.5" % "test"
libraryDependencies ++= Seq(
"org.scalatra" %% "scalatra" % ScalatraVersion,
"org.scalatra" %% "scalatra-json" % ScalatraVersion,

)
enablePlugins(SbtTwirl)
enablePlugins(ScalatraPlugin)
我不明白为什么，并且想知道如何解决这个问题。幸运的是，这似乎并没有引起任何具体的错误。或多或少只是个烦人。预先感谢。
