  3. " : Unsupported major.minor version 52.0"

    Make sure you use the right spigot jar, and that it's working with the java version you're using.

    You can use java 7 for 1.8.8 for example,
    and you can do java 8 for 1.12.2,
    or java 8 or 11 for 1.13.2, or 1.14.

  4. To add onto this, if OP is running Java 7, but using plugins compiled with Java 8 won't work
