[I] "Unable to find the root directory" in multi-module build [maven-mvnd]
calle2010 opened a new issue, #901:
URL: https://github.com/apache/maven-mvnd/issues/901
In different projects with multiple modules mvnd 1.0-m7 prints in the first line
Unable to find the root directory. Create a .mvn directory in the root directory or add the root="true" attribute on the root project's model to identify it.
But Maven 4.0.0-alpha-8 doesn't complain. In both cases Maven is started from the project root directory. Creating the ".mvn" directory doesn't mute the message printed by mvnd.
```
$ mvnd -1 -DskipTests clean compile
Unable to find the root directory. Create a .mvn directory in the root directory or add the root="true" attribute on the root project's model to identify it.

Thanks for the report, @calle2010!
Creating the `.mvn` directory should solve the issue. I wonder whether there some kind of git push/pull in between that ignores empty directories?
