stackoverflowの回答
StackOverFlowには、「"Use SBT shell for build and import"にチェックを入れる」という回答がありました。
Go to Preference > Build, Execution, Deployment > SBT > check "Use SBT shell for build and import" > Press OK You can now refresh SBT projects and it should work . if you want, you could uncheck "Use SBT shell for build and import" and it will also work
「requires sbt 0.13.5+」と書いてあるので、チェックを入れた方がいいんですかね？
今はまだよくわからないです。
