how to add jars for scala kernel

[git0114106]

how do I add jars to my kernel before it launches?.
Apart from standard libraries, the notebook is not picking up the ones in CLASSPATH
import org.apache.commons.io._ is giving me error
cmd0.sc:1: object apache is not a member of package org

You can add custom env variables to your kernels as follows:

• Create a file named .env in your workspace folder
• Add an entry as follows

CLASSPATH=XYZ

• Reload VS Code and run the kernel
• The env variable CLASSPATH will be available to the kernel
  Hope this helps.
