I run mvn generate-sources and get the following error

What the easiest / recommended way of installing tsc?

renaudpawlak commented 8 years ago

Normally, JSweet is supposed to install tsc automatically (through nodejs). It must have failed somewhere before that error. Can you send the full trace?

Follow-up: I have managed to reproduce the issue under Linux. So it is a Linux problem (it works under Windows). I will investigate more and get back to you.

Hi Martin!

Hopefully, the issue should be fixed! :) I am saying hopefully, because it is basically a permission issue under Linux, and it is always tricky to solve these, especially from Java. I had to change various things and I hope it will not regress...

So I am curious to hear your feedback... You may need to clean your local maven repo for org.jsweet. so that you get the new JSweet snapshot.

it works, thanks.

Great! I will update the documentation...
