Thanks for reporting! The current workaround is to use launch.json if using VS Code (other editors should also enable this in different ways) and defined jvm propeties there.

@tgodzik Okay, I created the following ./.vscode/launch.json:

{
  "version": "0.2.0",
  "configurations": [
    {
      "type": "scala",
      "request": "launch",
      "name": "Chuck Norris App",
      "mainClass": "objektwerks.ChuckNorrisApp",
      "args": [],
      "jvmOptions": ["--enable-preview", "--add-modules=jdk.incubator.concurrent"],
      "env": {}
    }
  ]
}

I then selected the run link in the objektwerks.ChuckNorrisApp source file --- but VSCode failed to pick up the specified jvm options. I also tried a few other variations on the jvmOptions, but nothing worked.

The reported error is:

Exception in thread "main" java.lang.ExceptionInInitializerError
        at objektwerks.ChuckNorrisApp.main(ChuckNorrisApp.scala)
Caused by: java.lang.UnsupportedOperationException: Preview Features not enabled, need to run with --enable-preview

        at objektwerks.ChuckNorrisApp$.<clinit>(ChuckNorrisApp.scala:11)

Have you or someone you know successfully used this technique? Thanks!

You need to run from the run menu. There is a drop-down to choose which configuration you want to run. You should see the created configuration name. I am on my phone now, but let me know if you have any issues. I will try to show a gif when I am on my computer

@tgodzik Indeed, selecting menu Run > Run Without Debugging works! :) The embedded run | debug source link does not. Thanks! ;)
