I have a project setup using Intellij Idea scala sbt.
sbtVersion = 1.2.8, scalaVersion = 2.13.0
I am trying to setup gatling but i get the following errors after i run the command :
gatling: test
[error] Uncaught exception when running tests: java.lang.NoClassDefFoundError: scala/collection/mutable/ArrayOps$ofRef [error] sbt.ForkMain$ForkError: java.lang.NoClassDefFoundError: scala/collection/mutable/ArrayOps$ofRef [error] at io.gatling.sbt.GatlingRunner.tasks(GatlingRunner.scala:31) [error] at sbt.ForkMain$Run.runTests(ForkMain.java:258) [error] at sbt.ForkMain$Run.run(ForkMain.java:144) [error] at sbt.ForkMain$Run.access$100(ForkMain.java:140) [error] at sbt.ForkMain.main(ForkMain.java:126) [error] Caused by: sbt.ForkMain$ForkError: java.lang.ClassNotFoundException: scala.collection.mutable.ArrayOps$ofRef [error] at java.net.URLClassLoader.findClass(URLClassLoader.java:381) [error] at java.lang.ClassLoader.loadClass(ClassLoader.java:424) [error] at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:349) [error] at java.lang.ClassLoader.loadClass(ClassLoader.java:357) [error] at io.gatling.sbt.GatlingRunner.tasks(GatlingRunner.scala:31) [error] at sbt.ForkMain$Run.runTests(ForkMain.java:258) [error] at sbt.ForkMain$Run.run(ForkMain.java:144) [error] at sbt.ForkMain$Run.access$100(ForkMain.java:140) [error] at sbt.ForkMain.main(ForkMain.java:126) [info] Simulation(s) execution ended.
