version := "0.1"
scalaVersion := "2.12.4"
libraryDependencies += "org.scala-lang.modules" %% "scala-parser-combinators" % "1.0.6"
I think i have excatly the same code like in tutorial. I don't understand what a problem and how to relosve this dependencies. Sbt plugin is downloaded by idea and versions of scala and sbt are the same like in tutorial
EDITED
here's idea.log and sby.last.log link

Cannot find command sbt: http://joxi.net/Q2KQqJKC9GQJNr
回答1:
I had faced the same problem by following that tutorial you mentioned. I am assuming that you are behind proxy.
so you need to add the http and https parameters in vm parameters.
edit the following : Run -> edit Configurations -> sbt Task -> "Run the program" -> VM Parameters
-Xms512M
-Xmx1024M
-Xss1M
-XX:+CMSClassUnloadingEnabled
-Dhttp.proxyHost=<proxy_ip> #eg: 10.1.2.3
-Dhttp.proxyPort=<proxy port> #eg: 8080
-Dhttps.proxyHost=<proxy_ip> #eg: 10.1.2.3
-Dhttps.proxyPort=<proxy port> #eg: 8080
If you don't know the proxy address, try the below, open chrome -> settings -> search proxy -> open proxy settings -> Lan Settings -> Proxy Server.. there is a possible that you can find over there :)
回答2:
Make sure you are using JDK Version 1.8. I was facing the same problem while importing one of my old projects and changing the custom location to JDK Version 1.8 helped me.
The location of your JVM is dependent on what version of OSX you are using. On newer versions of OSX/macOS, you can use this command to find the location of the JDK /usr/libexec/java_home -v 1.8.
