Output is not printed to the shell when executing commands from a script

[georgmittendorfer]

I cannot execute scripts anymore in spring shell 4.0.

The following worked in spring shell 3.x

shell:>script --file /home/user/my.script
Unable to run command script: Script command expects exactly one argument: the absolute path to the script file to execute.

When using the absolute path without --file:

shell:>script /home/user/my.script
Command script /home/user/my.script not found

Also relative paths didn't work.

Try using script -- /home/user/my.script, as the script command now requires an argument.

The syntax was changed from:

script --file /home/user/my.script

to

script -- /home/user/my.script

This is clearly documented here: https://docs.spring.io/spring-shell/reference/commands/builtin/script.html

Thank you, I didn't know about the -- syntax. Now the script executes but the output is not printed within the shell. Is there anything in addition that I need do to make it work like before?

(Edit: I run the script inside the interactive shell).

Additional slightly offtopic question: is version 4.x as production ready as version 3.x or should I wait with migrating? I mainly want to be able to use spring boot 4.x.

@georgmittendorfer Sorry, this is not question for me. This should be answered by maintainer @fmbenhassine

Still. Even with the modified syntax it doesn't properly work for me:

shell:>script -- /home/user/some.script
shell:>

There is no output shown inside the shell. I can see in the logs that the commands are executed.

The problem was that each command from the script file was executed in a separate, non-interactive shell runner using PrintWriter.nullWriter().
I've created a PR (#1275) fix and fixed it by passing the Script command’s output writer to each executed command.
