shebang stopped working after 0.1.18

[julienrf]

Version(s)

$ scala-cli --version
Scala CLI version: 0.1.18
Scala version (default): 3.2.1

Describe the bug

Scala-CLI ignores the “using directives” of my executable script that uses the shebang command.

To Reproduce

Consider a file Test.scala:

$ ls -l          
total 4
-rwxrwxr-x 1 julien julien 288 Dec  4 15:56 Test.scala

It contains a regular Scala-CLI script and uses the shebang command:

$ cat Test.scala 
#!/usr/bin/env -S scala-cli shebang
//> using scala "2.13.8"
//> using repository "https://artifacts.unidata.ucar.edu/repository/unidata-all"
//> using lib "edu.ucar:grib:5.3.1"

import ucar.nc2.dt.grid.{GeoGrid, GridDataset}

object Main {
  def main(args: Array[String]): Unit = ()
}

Note that the script uses Scala 2.13.8, and one library dependency.

Trying to run it (on Ubuntu):

$ ./Test.scala 
Compiling project (Scala 3.2.1, JVM)
[error] ./Test.scala:6:8: Not found: ucar
[error] import ucar.nc2.dt.grid.{GeoGrid, GridDataset}
[error]        ^^^^
Error compiling project (Scala 3.2.1, JVM)
Compilation failed

The import is not resolved, and the Scala version is wrong.

Note that the regression seems to be pretty recent as it was working not a long time ago.

Expected behaviour

Scala-CLI does take into account the using directives of the file.

Workaround

• Remove the shebang on the first line
• Run the script with scala-cli run Test.scala -- ...
