> If a {{<source>}} element in POM does not provide any value for the
> {{<directory>}} element, the default value is currently defined as
> {{src/${scope}/${lang}}}. This default value provides the familiar
> {{src/main/java}} and {{src/test/java}} default directories. However, if the
> {{<source>}} element contains a {{<module>}} element, the module name must
> appear somewhere in the default directory name, otherwise the source code of
> multi-modular projects will collide.
> Different conventions are possible:
> * OpenJDK uses {{src/${module}/}} for the main code and a non-obvious
> directory pattern for the tests.
> * [Project Jigsaw: Module System Quick-Start
> Guide|https://openjdk.org/projects/jigsaw/quick-start] uses
> {{src/${module}/}} for main code and does not mention tests.
> *
> [junit5-modular-world|https://github.com/junit-team/junit5-samples/tree/main/junit5-modular-world]
> uses {{src/main/${module}/}} for the main code and {{src/test/${module}/}}
> for the test code. However, it also uses {{module-info.java}} in test code,
> which I would like to discourage.
> * NetBeans Ant modular project uses {{src/${module}/main}} for the main code
> and {{src/${module}/test}} for the test code.
> I propose the NetBeans's convention with the addition of {{${lang}}. The
> default directory would then be {{src/${lang}/${module}/${scope}}} when the
> {{<module>}} element is present and non-blank.
> h2. Alternative
> If it is considered too premature to adopt a default directory name for
> modular project, we should at least throw an exception asking users to
> specify a directory explicitly if a {{<module>}} element is present. What we
> need to avoid is the status-quo, a default without module name.
