java.lang.NoClassDefFoundError when running activator command in IDEA terminal

Question

So this was all going well with my old computer but when I try to pack up my project on my new computer environment using "activator dist" or any other activator command in IDEA terminal, it shows:

java.lang.NoClassDefFoundError: activator/package$RichIO$

Error during sbt execution: java.lang.NoClassDefFoundError: activator/package$RichIO$

my sbt.version is 0.13.5 activator version is 1.3.12 and here is part of my build.sbt

name := "react-play"

version := "1.0"

lazy val `react-play` = (project in file(".")).enablePlugins(PlayJava)

scalaVersion := "2.12.4"

Thanks in advance

Answer 1

Okay so it seems that I solved my problem by updating my sbt.version from 0.13.5 to 0.13.17 and changing my jdk version to 1.8.0_201. Not sure which one did the trick though.
