JBang interactive option fails with `Unknown option: D`

[sberyozkin]

In Quarkus, after doing quarkus create cli --jbang and then moving to the generated code-with-quarkus and running jbang --interactive src/main.java reports:

[jbang] You can run the main class `io.quarkus.runner.GeneratedMain` using: userMain(args)
Unknown option: D

Note adding a package declaration to src/main.java makes no difference

That's because the generated path uses jshell and it runs the following:

/home/ggastald/.sdkman/candidates/java/current/bin/jshell -Djava.util.logging.manager=org.jboss.logmanager.LogManager --class-path=/home/ggastald/.jbang/cache/jars/main.java.3ecc6e5945ddb5560d324568ec2caae63febafbf794206fbadf0ad4b82c8290c.jar:...

Which I think it is missing a -R or -J:

/home/ggastald/.sdkman/candidates/java/current/bin/jshell -R-Djava.util.logging.manager=org.jboss.logmanager.LogManager --class-path=/home/ggastald/.jbang/cache/jars/main.java.3ecc6e5945ddb5560d324568ec2caae63febafbf794206fbadf0ad4b82c8290c.jar:...

BTW removing the flag or putting the -R or -J prefix still fails the execution with:

Error:
package io.quarkus does not exist
int userMain(String[] args) { return io.quarkus.runner.GeneratedMain(args);}
                                     ^---------------^

Is it missing users own jar ?

Btw. Even when we fix that we don't have a way to run quarkus non-blocking / in background so you can interact with it from jshell.

@stuartwdouglas you see a way to run quarkus in background and be able to interact with it from jshell ?

just saw https://github.com/bitterfox/JavaFXSupportsForJShell which use --execution flag on jshell to allow executoin on jfx thread....could be interesting to explore for quarkus too
