Description

When creating a groovy script for nixos I ran into an issue. Here is the script.

 

#! /usr/bin/env nix-shell
#! nix-shell -i groovy -p groovy

println "hello"

The script uses a second bash directive which tells nix-shell to run the script using groovy. Groovy gives the following error.

 

org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
/home/john/projects/netbeans/update-nix-dependencies.groovy: 2: unexpected char: '#' @ line 2, column 1.
   #! nix-shell -i groovy -p groovy
   ^

1 error

This seems to be a groovy issue and I was wondering how it could be fixed. There is a workaround for nix-shell described here. I'm willing to submit a pull request for this but I'm not sure where to start. Thanks!
