  8. I was able to compile it for 1.12 with gradle updating the ropisotories. Then I added 1.13 repositories, but the code gave me errors into only a class, so I changed a lot the code but when I try to create a world with the plugin, it gives me a runtime error. The reason is simple: in the spigot jar a class changed. Here's a page where I posted all the informations about that error. I hope you could help me, I have no idea about how to fix yet T_T

  9. Try these two classes.

    Change the field to d


    I see the problem. Worldprovider is Not hold in the class anymore.

  10. Yes it's right and I tried with "d" but the variable d is a boolean
  11. Would you have any idea about how to avoid that problem?
  12. Hello.
    I tried to compile the entire project provided by
    ysl3000 fork (here:

    It compiles without errors, but when I load the plugin in my craftbukkit-1.13-pre7 server I see this message:
    "Islandcraft does not currently support this CraftBukkit version"
    And if I look in IslandCraft-NMS-v1_13_R1 folder I see that the build folder in which you should find the compiled jar is missing. So it seems that IslandCraft-NMS-v1_13_R1 has not been compiled by gradle. (Which is what ysl3000 writes in his github repository "It compiles but doesn't drop a finished jar". )
  13. Hello again, I spent some time trying to resolve the problem, and I think I succeded. I can compile Islandcraft plugin linked to craftbukkit-1.13.
    I loaded the plugin in my server and it seems working without errors.
    You can try yourself, I have just created a git repository here:
    You can download the compiled jar to direct test it from here:
    Let me know if it really works because I am not sure of it.

  15. Ok, I merged your patch in my code. I tried again in my windows server and I entered with a 1.13 mc client, everything seems working, Let me know if you test it.
  16. I need to force start the server with Java 8. At the moment I'm searching the dependencies so that the plugin can run on Java 9+.
  17. Even the current version of the plugin boots and runs without errors. The issues are in the worlds themselves, where it seems they are not generated as they used to be. So, the plugin probably isn't working correctly.
  18. I'm working for him on this and I'm able to install the custom World chunk manager and everything but when I join the world the game crash giving a client npe
