Command error when COURSIER_INSTALL_DIR has nested directories #3117
Description
The cs setup in earlier versions would prompt to customize COURSIER_INSTALL_DIR and COURSIER_CACHE. There were no instructions about the restrictions, so I set them as followed in system environment properties:
COURSIER_INSTALL_DIR=C:\Coursier
COURSIER_CACHE=C:\Coursier\Cache
I thought the COURSIER_INSTALL_DIR points to the root directory of the installation, and was expecting some other directories would be created under this directory (e.g., bin, lib, etc.) like common practice in make install. So I placed the Cache directory in this Install directory.
After this cs list and cs update will raise error and the error message is not easy to understand.
Exception in thread "main" java.io.FileNotFoundException: C:\Coursier\Cache (Access is denied)

It would be great to
- filter out directories when examine files in
cs listorcs update, or - prompt for incorrect setup when install dir contains other directory, or
- have some documentation on how to set the path configuration environment variables.
