Hi,

I ran accross the exact same problem which blocks me a lot in my work.

I described it in #201 a few days ago.

If you or anyone happens to solve this problem I'd be glad to hear about it.

Thank you.

Hi again,

I found a way to go around this error. I reported what I did in my own issue #201 and put my solution in a PR #203.

Have a good day.

Lovely, the Closure Library team made a change that requires '--exclude' be used, even if it is empty. Fixed via https://github.com/google/blockly-games/commit/530c6926ed7baf662ad845350ef8b4344e6f482f

Thanks for the report.
