Ian Dunbar commented on MNG-6359:
---------------------------------
Thanks for trying to reproduce. I removed the .m2 folder entirely, but it still
has the same issue. I'll see if I can reproduce on a different machine.
Is there a way to trace the evaluation of the artifact resolution? I could then
compare why running from cmd.exe on the same machine doesn't experience the
issue.

> Environment: Run from gitbash
> GNU bash, version 4.4.12(1)-release (x86_64-pc-msys)

> The attached multimodule example fails to build when run from gitbash on
> windows 10. I've derived it from this example
> [https://github.com/jamesward/maven-multi-module-example] but modified to
> match my scenario.
> It works fine from CMD shell on the same machine with the same Apache Maven
> install. It's only with gitbash that the issue occurs. I see that the mvn
> launcher has specific sections for mingw derived shells like gitbash, so
> possibly something is wrong there.
>
> The issue occurs when the project has no artifacts yet in .m2 repo. So please
> remove .m2/repository/com/jamesward prior to testing.
> The transition from working to non-working in gitbash is with the addition of
> the parent section in the toplevel pom.xml, so there seems to be something
> wrong with the parent resolution in the toplevel when run from gitbash
> Steps:
> * remove .m2/repository/com/jamesward
> * unzip the example
> * run gitbash in that folder
> * mvn clean install
> * *fails to build*
> *
> * change to cmd.exe
> * mvn clean install
> * *builds correctly*
