Using quay.io images:

docker run -v `pwd`:/ws --workdir=/ws quay.io/jbangdev/jbang-action helloworld.java

Github Action

Inputs

Key Example Description
trust https://github.com/maxandersen Host pattern to add to be trusted before the script are executed.
jbangargs --verbose Arguments to pass to jbang before the script.
script hello.java File, URL or alias referring to script to run
scriptargs --token ${GITHUB_TOKEN} Arguments to pass to the script. Note: due to how github actions + docker arguments containing spaces gets treated as seperate arguments no matter how much quoting is done. If you need argument with spaces better to extend the docker file and call jbang directly.
