当我尝试将代码上传到EC2 ubuntu实例时，我遇到了问题。我检查了我的java版本，scala版本和sbt版本，以及所有SEEMS到位，但我收到的错误似乎是版本问题。
这是我的build.sbt
name := "SentenceParserTimingStudy"
version := "1.0"
scalaVersion := "2.11.7"
mainClass in (Compile, run) := Some("TimingTester")
unmanagedJars in Compile += file("lib/stanford-srparser-2014-10-23-models.jar")
libraryDependencies += "edu.stanford.nlp" % "stanford-parser" % "3.5.2"
libraryDependencies += "edu.stanford.nlp" % "stanford-corenlp" % "3.5.2"
libraryDependencies += "io.argonaut" %% "argonaut" % "6.1-M4" changing()
libraryDependencies += "edu.stanford.nlp" % "stanford-corenlp" % "3.5.2" artifacts (Artifact("stanford-corenlp", "models"), Artifact("stanford-corenlp"))
我检查了我的java和scala版本，它们似乎是正确的
java version "1.8.0_66"
Java(TM) SE Runtime Environment (build 1.8.0_66-b17)
Java HotSpot(TM) 64-Bit Server VM (build 25.66-b17, mixed mode)
Scala code runner version 2.11.7 -- Copyright 2002-2013, LAMP/EPFL
然而，每当我运行我的代码时，我都会收到此错误
