[CLI] --help option prints out SDK errors

[Sahand-H]

Running blang --help leads to the following output (only grabbed a snippet of it) on macOS:

Compilation {
  Note: this may take more time the first time the command is called
    as some dependencies will be downloaded.
  Using blang SDK version 1.33.1

[alexandrebouchard]

Is it possible that the command was ran in a directory within blang SDK?

[Sahand-H]

This may have been a little premature. The errors were a result of running the command outside a contained directory (ran on desktop) and multiple SDK installs are the likely reason.

[alexandrebouchard]

Still interested in figuring out how if we can at least improve the error message. Can you replicate and let me know what was in the directory that it was ran in? Thanks!

Similar errors can be reproduced as follows (assuming CLI already set up)

mkdir test; cd test
git clone [email protected]:ubc-stat-ml/blangDemos.git
git clone [email protected]:ubc-stat-ml/blangExample.git
blang --help

I think a simple fix would be to recursively check for build.gradle in child directories.
