1.14.4 Bungee classes missing

Hi, so I wanted to use packets but when I type in PacketPlayOutSometing it says there are no such classes? Am I missing someting? Maybe some maven stuff or libraries

 

So what should I add to my pom.xml?

 

I added this to my pom.xml

Code (Text):

<dependency>
            <groupId>net.md-5</groupId>
            <artifactId>bungeecord-api</artifactId>
            <version>1.14-SNAPSHOT</version>
        </dependency>

But the classes are still missing

 

It doesn't accept just spigot.
