Java Modules are a feature of Java itself, available since Java 9, that allows for better encapsulation.

In Gradle, each _source set_ containing Java sources can be turned into a module by adding a `module-info.java` file.
Typically, in a project with Java Modules like this one, the _main_ source set of a subproject represents a module.

```
src
└── main
    └── java

stderr 'directory a[\\/]c is contained in a module that is not one of the workspace modules listed in go.work. You can add the module to the workspace using:\n\tgo work use a'

cd a/c
! go run .
stderr 'current directory is contained in a module that is not one of the workspace modules listed in go.work. You can add the module to the workspace using:\n\tgo work use \.\.'

cd ../..
! go run .

        // We recompile all module-info.java also for unrelated modules, but we don't recompile unrelated classes
        impl.recompiledFqn("my.module.first.b.B", "my.module.second.c.C", "my.module.first.module-info", "my.module.second.module-info", "my.module.unrelated.module-info")
