Minecraft 1.15.2 needs Java 8
1.15.2 was a quieter update that fixed a lot of what went wrong performance-wise in 1.14. Forge and Fabric both support it, although neither has much of a library here.
Java version required
8or newer
An older Java will not start it. A much newer Java normally does, but that is up to the server software rather than Minecraft.
Availability
Paper is available for 1.15.2
It accepts Bukkit / Spigot / Paper plugins.
Will the file I downloaded work?
Mods and plugins are two different things that both come as a .jar. Use the wrong kind and there is usually no error: the server boots and the content is simply missing.
running on Paper
No. Forge is a mod platform and Paper runs plugins — two separate systems that just share a file extension. Nothing loads, and you get no warning.

Things to know about this version
These days it mainly serves as a waypoint — many packs that started on 1.14 wrapped up on 1.15.2 before the community converged on 1.16.5. Starting fresh, you would almost always take 1.16.5 instead: same Java, much more content.
