[MNG-8460] All Prompter use seems busted

[jira-importer]

Tamas Cservenak opened MNG-8460 and commented

With current master (575ad37) seems all prompter actions are defunct:

• mvn release:prepare
• mvn versions:set

These all stalls forever (without any prompt/output) waiting for user input... something is borked.

Prompt is not shown, but input is picked up. Still, this is bad, as user have no clue what the input should be.

What I have so far: Prompters do work if user specifies --raw-streams in CLI.

But, this is wrong IMHO, as users should not do "extra switches" to make Prompting work. Broader context is that --raw-streams was originally mvnd parameters "ported to mvn" (740100b). But the effect of it was this:

• this issue (Prompters)
• users also reported that mvn help:evaluate \-Dexpression=xxx \-DforceStdout does not work without --raw-streams

I kinda feel like "raw-streams" option default value should be different between mvn and mvnd (unsure about the MT logging part)...

There is also a PR #2006 that makes things work, somewhat: mvn versions:set w/o params to use prompter produces this now:

So prompt is visible now (input did work, it was just the prompt and the fact that Maven "wants something from user" that was the problem.

Will go with PR for now, and we will see later what to do. The PR makes it "work" (prompt is visible) but is a bit ugly, as prompt is terminated with newline.
