Here you'll see how to serve those files yourself, in the same FastAPI app, and configure the docs to use them.

### Project file structure { #project-file-structure }

Let's say your project file structure looks like this:

```
.
├── app
│   ├── __init__.py
│   ├── main.py

 * - The target JVM version
 * - Workarounds which may affect the way the compilation is performed

 * The compilation workarounds include:
 * - Using JDK internal classes
 * - Using Java standard library APIs that were introduced after the JVM version they are targeting
 *
 * All of these workarounds should be generally avoided, but, with this data we can configure the
 * compile tasks to permit some of these requirements.
