ProvidersLib

- Actionbar doesn't work at all on Glowstone 1.10.2 build (tested 20/11/2016)
- Title sends without colors using PaperSpigot API method and /glowstone:title command is broken on Glowstone 1.10.2 build (tested 20/11/2016)
- Newer plugin versions don't play good with Glowstone internals at all

As I am lazy and I use Levitate to register commands, it has one awful bug. It isn't compatible with Essentials items.csv (apparently it uses that to implement one ItemStack syntax or whatever), thus ProvidersLib's commands may not work at all. Either don't enable commands from config, clear Essentials' items.csv or don't use Essentials at all (yes, there are alternatives and I believe everybody can even cook their own).
I am looking into alternatives (looking at Aikar's commands library)

This plugin is totally broken on it. It is something related to Guice, but I don't have time to look why it breaks.

Plugins which provide Actionbar functionality:

• ActionBarAPI
• BountifulAPI
• TitleManager
• Spigot's own API (not available under 1.8.8)
• ProtocolLib
• Mojang (as of 1.11)

Falls back to no-op method, if any of those couldn't be found

Plugins which provide Chat functionality:

• Vault

Falls back to no-op method, if any of those couldn't be found

Plugins which provide Permissions functionality:

• Vault
• Bukkit's own API

Bukkit's own API is fallback here. It only works with operator status (/op)

Plugins which provide Spawnpoint functionality:

• Multiverse-Core
• Bukkit's own API

Will fall back to Bukkit API if no other providers are found. Hint: /setworldspawn

Plugins which provide Title functionality:

• BountifulAPI
• Mojang (universial, works everywhere)
• PaperSpigot's own API
• TitleAPI
• TitleManager
• ProtocolLib
• ProtocolSupport

Falls back to Mojang method (aka /title command)

Plugins which provide Vanish functionality:

• Essentials
• Super/PremiumVanish

Falls back to no-op provider, which returns always false

Stub plugins (will replace some plugins completely, without needing to rewrite plugins to use my API)

• TitleActionbarAPI (obsolete and broken on 1.10+ - but famous Parkour plugin's rewrite uses it)
• ActionbarAPI (seems like popular plugin)
• TitleAPI (same goes for here)
• BountifulAPI (ActionbarAPI + TitleAPI)

Note: stub plugins will activate if original plugin is not installed

Get instance in your plugin and example code

@Inject Actionbar actionbar;
@Inject Chat chat;
@Inject Permissions permissions;
@Inject Spawnpoint spawnpoint;
@Inject Title title;
@Inject Vanish vanish;

@Override public void onEnable(){
        RegisteredServiceProvider<
eu.mikroskeem.providerslib.api.Providers> rsp = getServer().getServicesManager()
                .getRegistration(
eu.mikroskeem.providerslib.api.Providers.class);
        if(rsp == null){
            getLogger().severe("ProvidersLib wasn't initialized!");
            getServer().getPluginManager().disablePlugin(this);
            return;
        }
        Injector injector = rsp.getProvider().getInjector();
        injector.injectMembers(this);
}

@EventHandler
public void on(PlayerJoinEvent event){
    Player player = event.getPlayer();
    actionbar.sendActionbar(player, "asuh dude");
    getLogger.info(chat.getPrefix(player));
    getLogger.info(permissions.playerGetPrimaryGroup(player));
    player.teleport(spawnpoint.getSpawnpoint(world));
}

This plugin is based on Google Guice, so you're not limited to using this example.
See classes in https://git.mikroskeem.eu/mikroskee.../src/main/java/eu/mikroskeem/providerslib/api for more methods

T hey're useful for debugging. It tells you what provider is used and invokes its method.

/testactionbar <player> <seconds> <text>

Maven include:
NOTE: API dependency version won't update that often like plugin is updated. I will say when to update API version in your POM

<dependency>
          <groupId>eu.mikroskeem.providerslib</groupId>
          <artifactId>api</artifactId>
          <version>0.0.5-SNAPSHOT</version>

PROBLEM 1: People have reported me that my repository doesn't work
(only under Windows?)
SOLUTION: run mvn -U (your project goals)
