The download page of scala-sbt.org provides the RPM package.
You can install the sbt rpm package by
yum. We only need the URL to the RPM package. Here, let take version
0.13.1 as a example.
# yum localinstall http://repo.scala-sbt.org/scalasbt/sbt-native-packages/org/scala-sbt/sbt/0.13.1/sbt.rpm
yum will download the package and install it.
After installation, you can run
sbt will download and configure itself.
Or use the excellent sbt-extras: https://www.systutorials.com/qa/858/how-to-install-multiple-versions-of-sbt-on-my-linux-host to automatically manage sbt versions used/needed.
