Problem Received status code 403 from server: Forbidden

I have add
`maven {
url 'https://api.mapbox.com/downloads/v2/releases/maven'
authentication {
basic(BasicAuthentication)
}
credentials {
// Do not change the username below.
// This should always be `mapbox` (not your username).
username = "mapbox"
// Use the secret token you stored in gradle.properties as the password
password = project.properties['MAPBOX_DOWNLOADS_TOKEN'] ?: ""
}
}`

And have add

`implementation "com.mapbox.navigation:ui:1.5.1"`

This return

Start with the Gradle project configuration and gradle.properties, focusing on the MAPBOX_DOWNLOADS_TOKEN credentials used for the Mapbox Maven repository. Run :app:assembleDebug and inspect resolution of com.mapbox.navigation:ui:1.5.1. Done means the dependency resolves without the 403 error and the debug build proceeds.
