The filenames of some of your mods suggests you are not getting them from official sources, please read my signature for more info on why this is a bad thing.
At least one of your mods is broken/poorly made and will not work on a server.
Why were you trying to compile manually with javac?
Your current version of Gradle(or the gradle wrapper) is incompatible with Java 11, try Java 8 as that is what Minecraft targets.
This is the bit that concerns me:
