sbt assembly cannot create jar getting java.lang.UnsupportedOperationException-CodePudding

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:

CodePudding user response：

It was deprecated and for removal in 17 so in 18 it is not expected to be working ref: https://openjdk.java.net/jeps/411 can you try

System.setSecurityManager(null)
