Allay Replication
A rather basic plugin that implements (as close to vanilla as possible to achieve in a day) Allay replication/duplication mechanics in 1.19 for those who do not wish to update to 1.19.1

In-game Usage
To trigger any action the Allay must be leashed and unleashed (or just unleashed if already leashed). The plugin then checks the following conditions:

• A jukebox must be playing within a 7 block radius of the Allay (analogous to the vanilla dancing requirement)
• A block of amethyst must be within the same 7 block radius (analogous to handing over an amethyst shard)
• Has the Allay been replicated recently - after each replication the original and replicated Allay have a 2.5 minute cooldown before they can replicate again.

Important
This plugin was made in less than a day for a private server I play on. LTS is not guaranteed (though no breaking changes can be expected). For efficiency, the PaperMC forked library is used. If your server does not use Paper then this plugin will not work.
