The problem is that if you have a multimodule build (lets say 300 modules)
and use multithreading (so build messages are interleaved), and one of the
projects fail in the middle you have a huge logfile full of "banned" messages
but you need to find out what/where it actually fails, so the message without
any context is quite useless and even if you find the erroneous project its not
very helpful. So I though showing it at tat time might be more useful.
Another approach would be to simply not display the message at all, and
instead give a summary at the end of build, e.g. ```
The following projects where not build due to previous failures:
- a (depends on x that failed)
- b
- c (depends on b that was banned)
```
sadly currently this information is somehow spread across some places and
I'm not sure why e.g. a listener was used instead of printing the message
directly on `blacklist()` ...
regarding `fae`/`ff` I think we can add such message of course but I didn't
wanted to complicate things for a first draft, if you think its usefull I think
it is quite easy to add,
> Message "This project has been banned from the build due to previous
> failures." is too unspecific

> Currently if a multimodule build fails (either fast or at the end), the user
> gets a message in the log that reads:
> {quote}This project has been banned from the build due to previous
> failures.{quote}
>
> this is correct but does not give a hint *what* has failed and one needs to
> investigate the build logs to get more details.
> Instead the message should show the actual project that make it impossible to
> build this and is the reason fro this project being banned.
