Build Requirements

Since TrueDiscordLink uses NMS, you need to have all supported versions of NMS available.

1. Install JDK 17 and JDK 8.
2. Download BuildTools from Spigot
   1. If you're on Windows, I've written a batch script which will run through and build all of the required versions.

      @ECHO OFF
      SET JAVA8_PATH="C:\Program Files\Eclipse Adoptium\jdk-8.0.372.7-hotspot\bin\java.exe"
      SET JAVA17_PATH="C:\Program Files\Eclipse Adoptium\jdk-17.0.7.7-hotspot\bin\java.exe"
      %JAVA17_PATH% -jar BuildTools.jar --rev 1.20.1 --remapped
      %JAVA17_PATH% -jar BuildTools.jar --rev 1.19 --remapped
      %JAVA17_PATH% -jar BuildTools.jar --rev 1.18.2 --remapped
      %JAVA17_PATH% -jar BuildTools.jar --rev 1.18.1 --remapped
      %JAVA17_PATH% -jar BuildTools.jar --rev 1.17.1 --remapped
      %JAVA8_PATH% -jar BuildTools.jar --rev 1.16.5 --remapped
      %JAVA8_PATH% -jar BuildTools.jar --rev 1.16.3 --remapped
      %JAVA8_PATH% -jar BuildTools.jar --rev 1.16.1 --remapped
      %JAVA8_PATH% -jar BuildTools.jar --rev 1.15.2 --remapped
      %JAVA8_PATH% -jar BuildTools.jar --rev 1.14.4 --remapped
      %JAVA8_PATH% -jar BuildTools.jar --rev 1.13.2 --remapped
      %JAVA8_PATH% -jar BuildTools.jar --rev 1.13 --remapped
      %JAVA8_PATH% -jar BuildTools.jar --rev 1.13 --remapped
      %JAVA8_PATH% -jar BuildTools.jar --rev 1.12.2 --remapped
      PAUSE

   2. If you're on a different machine, you'll need to manually run the BuildTools utility with the --remapped argument for all of the following versions:

      (Java 8)
      1.8
      1.8.3
      1.8.8
      1.9.2
      1.9.4
      1.10.2
      1.11.2
      1.12.2
      1.13
      1.13.2
      1.14.4
      1.15.2
      1.16.1
      1.16.3
      1.16.5
      
      (Java 17)
      1.17.1
      1.18.1
      1.18.2
      1.19
      1.20.1
      

3. Finally, set the SERVER_DIRECTORY environment variable in your IDE to a path to a test server (not the plugins folder, but the server's container folder).
