Paper requires Java 8!
Download Java 8 here, from oracle
Java 8 is strongly recommended for ALL servers. If your host is still using Java 6 or 7, please ask them to upgrade!
Server Admins do not need to build Paper to use it, as we provide a ready to use jar file!

This jar does not violate the DMCA against CraftBukkit as it does not ship the Minecraft Server. It distributes a patch file, that the jar will then download Minecraft Vanilla server for you, and apply the patches to it.
Developers may download the Paper repo and then run
./paper jar to build a jar file.
JDK8 is required.
