I am using
scala 1.12.10 akka 2.6.3 addSbtPlugin("io.spray" % "sbt-revolver" % "0.9.1") addSbtPlugin("com.eed3si9n" % "sbt-assembly" % "1.1.0")
However when executing sbt assembly
I am getting:
java.lang.UnsupportedOperationException: The Security Manager is deprecated and will be removed in a future release at java.base/java.lang.System.setSecurityManager(System.java:416) at sbt.TrapExit$.installManager(TrapExit.scala:53) at sbt.StandardMain$.runManaged(Main.scala:109) at sbt.xMain.run(Main.scala:76) at xsbt.boot.Launch$$anonfun$run$1.apply(Launch.scala:111) at xsbt.boot.Launch$.withContextLoader(Launch.scala:131) at xsbt.boot.Launch$.run(Launch.scala:111) at xsbt.boot.Launch$$anonfun$apply$1.apply(Launch.scala:37) at xsbt.boot.Launch$.launch(Launch.scala:120) at xsbt.boot.Launch$.apply(Launch.scala:20) at xsbt.boot.Boot$.runImpl(Boot.scala:56) at xsbt.boot.Boot$.main(Boot.scala:18) at xsbt.boot.Boot.main(Boot.scala) [error] [launcher] error during sbt launcher: java.lang.UnsupportedOperationException: The Security Manager is deprecated and will be removed in a future release
