Gradle coordinates:

compile('com.github.prominence:openweathermap-api:2.1.0')

How to use:

Firstly, you need to create the instance of OpenWeatherMapClient class:

OpenWeatherMapClient openWeatherClient = new OpenWeatherMapClient(API_TOKEN);

where API_TOKEN is your token(you can get it here) as String.

Currently, available APIs are:

currentWeather()
forecast5Day3HourStep()
oneCall()

Default(more or less) customization points:

...
// response language
.language(Language.RUSSIAN)
...
// response units of measure
.unitSystem(UnitSystem.IMPERIAL)
...

Available output forms:

asJava()
asJSON()

Additional output forms, available for several APIs:

asXML()
asHTML()

All response forms can be in sync and async variants.

Current weather data

Examples:

final String weatherJson = openWeatherClient
        .currentWeather()
        .single()
        .byCityName("Minsk")
        .language(Language.RUSSIAN)
        .unitSystem(UnitSystem.IMPERIAL)
        .retrieve()
        .asJSON();

final Weather weather = openWeatherClient
        .currentWeather()
        .single()
        .byCityName("Minsk")
        .language(Language.RUSSIAN)
        .unitSystem(UnitSystem.METRIC)
        .retrieve()
        .asJava();

final List<Weather> weatherList = openWeatherClient
        .currentWeather()
        .multiple()
        .byCitiesInCycle(Coordinate.of(55.5, 37.5))
        .language(Language.GERMAN)
        .unitSystem(UnitSystem.IMPERIAL)
        .retrieve()
        .asJava();

final CompletableFuture<String> weatherXmlFuture = openWeatherClient
        .currentWeather()
        .single()
        .byZipCodeAndCountry("220015", "by")
        .language(Language.RUSSIAN)
        .unitSystem(UnitSystem.METRIC)
        .retrieveAsync()
        .asXML();

You are able to set preferable options(via chain methods) and execute appropriate request.
