Dokka generates the documentation for each module independently. Until now, we used our custom Gradle plugin to combine the modules together. However, that lead to multiple problems (#21, #18). The structure of the project was: ``` + tree docs/website/docs/api docs/website/docs/api ├── -example%20app │   ├── index.md │   ├── opensavvy.dokka.material.mkdocs.example │   │   ├── index.md │   │   └── main.md │   └── package-list ├── -library%20module │   ├── index.md │   ├── opensavvy.dokka.material.mkdocs.example │   │   ├── -example │   │   │   ├── -example.md │   │   │   ├── counter.md │   │   │   ├── foo.md │   │   │   └── index.md │   │   ├── -example-alias │   │   │   └── index.md │   │   ├── -example.md │   │   ├── another-top-level-function.md │   │   ├── foo2.md │   │   ├── index.md │   │   └── top-level-function.md ``` Note the URL-encoded `%20` in the module names: they were using the Dokka pretty-print name instead of its technical name. For a real like example, here is an URL from the KtMongo documentation: ``` https://ktmongo.opensavvy.dev/api/-kotlin%20-b-s-o-n%20%E2%80%A2%20-based%20on%20the%20official%20-mongo-d-b%20implementation/index.html ``` Whereas, ideally, it should be: ``` https://ktmongo.opensavvy.dev/api/bson-official/index.html ``` which is much easier to read, and also more SEO-friendly. Also, all links to/from module header pages were broken because of our incorrect implementation of `LocationProvider`. With this MR, we have a proper aggregation plugin configured, which can solve all these problems. Here is the new structure: ``` + tree docs/website/docs/api docs/website/docs/api ├── example-app │   ├── index.md │   └── opensavvy.dokka.material.mkdocs.example │   ├── index.md │   └── main.md ├── example-core │   ├── index.md │   └── opensavvy.dokka.material.mkdocs.example │   ├── -example │   │   ├── -example.md │   │   ├── counter.md │   │   ├── foo.md │   │   └── index.md │   ├── -example-alias │   │   └── index.md │   ├── -example.md │   ├── another-top-level-function.md │   ├── foo2.md │   ├── index.md │   └── top-level-function.md ``` Thanks to the help of the Dokka team in https://github.com/Kotlin/dokka/issues/4074.
