"Vous venez de faire du café."

Translation: You just made coffee.

[GloriaLuisetto]

Why not "you've just made coffee" ?
Is it simply because of the contraction, or is it actually wrong to use a present perfect?

[CommeuneTexane]

That answer should be accepted. If it happens again, could you please take a screen shot and file a bug report? There may be a problem with the system recognizing contractions.

The system tends to accept possessive contactions, but less often verb contractions

Why is it de faire and not just faire?

[CommeuneTexane]

The fixed expression is "venez de" + the infinitive verb. Venir (conjugated) + de + the infinitive means "just did" something or something just happened. This is the near past. You can read about it in the Tips and Notes for this skill.

[JudithMett2]

Just realised that the verb 'venir' is 'venir de' and that dictates the usage of 'de' or otherwise.

What is difference for "going to make coffee" vs "just made coffee"

[CommeuneTexane]

I'm going to make coffee. → Je vais faire du café.
I just made coffee. → Je viens de faire du café.

Use aller for future events and venir de for near past ones.
