Description

With Poetry 2.1, any output made to stdout in the execution of the tool.poetry.build.script is not outputted to the terminal. This seems to be on purpose because as an error occurs, the output is fully displayed. However, there is no documentation on it, neither on this being intentional nor on how to forward an output directly.

Using the obvious verbose or debug flags (v/vv/vvv) does not change anything.

Documentation or even a hint on how to enable output to stdout would be highly appreciated

I expect poetry has just become more consistent - treating its own build as less of a special case - and this is essentially duplicate #2057
