Failed at Download Sources in NavigationView.class at Mapbox

Dieses Issue hat noch niemand übernommen.

**Android API: 29**
**Mapbox Navigation SDK version: 1.0.0**

I'm developing an Android Studio app with navigation using Mapbox.
My problem is that I cannot have the source of NavigationView. I mean, instead of NavigationView.java I have NavigationView.class with this message on the top:
>Decompiled .class file, bytecode version 52.0(java 8).
>
with the options of **Download Sources** and **Choose Sources**.
When I choose the option of **Download Sources** I have the following error:
```Executing tasks: [DownloadSources] in project /****/****/****/****/****/****

> Task :app:DownloadSources FAILED
1 actionable task: 1 executed

FAILURE: Build failed with an exception.

* Where:
Initialization script '/private/var/folders/8m/x8f28hgx685g1cm7zy_dxbbr0000gn/T/ijmiscinit12.gradle' line: 20

* What went wrong:
Execution failed for task ':app:DownloadSources'.
> Could not resolve all files for configuration ':app:downloadSources_fef929a7-720c-4d1b-b94c-6ee7e6d79f4e'.

```

I found a file called *Gradle__com_mapbox_navigation_ui_1_1_0_aar.xml* where it has the following content:
```

```
And I realise that in the line where it says
>library name="Gradle: com.mapbox.navigation:ui:1.1.0@aar"
>
is where it is the problem. How can I solve this?
PD: I have tried **Choose source** and choose the source file but it doesn't make anything.
PD 2: In my build.gradle I am using implementation ```'com.mapbox.navigation:ui:1.1.0'```
Thanks! :)

### Expected behavior
Navigation starting
### Actual behavior
Navigation doesn't start

Beginne mit der build.gradle der App und ihrer Abhängigkeit com.mapbox.navigation:ui:1.1.0 und reproduziere anschließend den Fehler der Aufgabe :app:DownloadSources. Untersuche, wie NavigationView als kompilierte Klasse aufgelöst wird und ob das aufgeführte Sources-Artefakt verfügbar ist. Erledigt ist die Aufgabe, wenn Quellen angehängt oder heruntergeladen werden können und die Navigation wie erwartet startet.
