sbt assembly cannot create jar getting java.lang.UnsupportedOperationException

Question

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:

running java 18

java -version
openjdk version "18" 2022-03-22
OpenJDK Runtime Environment (build 18+36-2087)
OpenJDK 64-Bit Server VM (build 18+36-2087, mixed mode, sharing)

Answer 1

Using java 8 solved this issue as AminMal suggested

Answer 2

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)

I also encountered this problem while using Java 19 and Java 18. After that, I downloaded Java 17 and configured the Project Structure, and the problem went away. Steps I took:

(1) Download Java Development Kit version 17, Google search "download java 17".

(2) To install, I run the downloaded file "jdk-17.0.6_windows-x64_bin.exe" (for Windows).

(3) Configure to use Java 17, go to
File -> Project Structure -> Project -> (dropdown) SDK
and you'd see the installed Java 17 under "Detected SDKs"

Answer 4

I encountered this issue when checking out an older Scala project. The solution was to change the project/build.properties file.

Before:

sbt.version=1.2.4

After:

sbt.version=1.6.2
