エラーが発生しますthere were 15 feature warning(s); re-run with -feature for details：

build.sbtで
scalaVersion := "2.10.4"
sbt as を実行しても、そのエラーが何なのかわかりません$ /usr/local/sbt/bin/sbt -feature。
$ /usr/local/sbt/bin/sbt -feature
[info] Loading project definition from /home/alex/Documents/projects/my_app123/project

$
JDK1.7です
エラーとは何ですか?どうすれば修正できますか?
更新：
build.sbt
scalacOptions in ThisBuild ++= Seq("-unchecked", "-deprecation")
またはsbt自体で：
> set scalacOptions in ThisBuild ++= Seq("-unchecked", "-deprecation")
エラーは同じままです。
