Adding as a plugin dependency
Now that you've added uQueue to your dependency manager, you should tell BungeeCord to load your plugin AFTER uQueue is loaded, by adding uQueue as a (soft)depend. If your plugin absolutely needs uQueue, you should use a depend. If it supports an optional integration, you shoudl use a softdepend.
Depending on which type of depend you're going to be looking, take a look at these example bungee.yml files.
Softdepend example
name: ExamplePlugin
version: 1.0.0
author: author
main: your.main.path.here
softdepends: [uQueue] # The plugin CAN integrate with uQueue, but doesn't NEED it.
Depend example
name: ExamplePlugin
version: 1.0.0
author: author
main: your.main.path.here
depends: [uQueue] # The plugin MUST integrate with uQueue.

Now that you've added the plugin as a BungeeCord dependency, you can start interacting with it via code.
