Native, C-based Bukkit plugin API. Please don't actually use this.



This plugin requires Java 12. This is purely to hopefully keep the number of people who try to use this lower.

The JAVA_HOME environment variable must be set to point to the JDK 12 properly for cmake to properly pick up the correct JDK location at build time.


You need the JDK installed and setup as described above, and cmake, make, and gcc. These should all be easy to install with your package manager.

./gradlew clean build


You need the JDK installed and setup as described above, and cmake, make, and gcc:

brew install cmake

Assuming you have XCode installed already:

xcode-select --install

The you should be able to build the plugin:

./gradlew clean build

Windows (MSVC)

Windows is the most complicated setup process, due to its strange environment. You need to have Visual Studio 2017 installed with the MSVC toolchain. Selecting Desktop development with C++ in the Visual Studio installer will select all of the necessary packages.

Open the x64 Native Tools Command Prompt for VS 2017 Command Prompt configuration from the Start Menu. Visual Studio creates this to provide a shell with the developer tools pre-defined on the path. Once open, run the command set. This will output all of the environment variables, many of which are not set in a standard Windows environment and are required for MSBuild. Copy the output of the set command and paste it into a file called env.txt in the root of this project. The Gradle build script will read it and use it to set the environment when calling cmake and MSBuild commands.

Note you'll need to re-do this setup any time Visual Studio updates.

Make sure the JAVA_HOME environment variable is set properly in the above env.txt.

Check to make sure you don't have any registry keys in HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\ pointing to any non Java 12 JDK. This is handled by the JAVA_HOME environment variable, so you don't need these registry keys at all, and you should delete them. Some JDK installers add these keys. Unfortunately, though it shouldn't behave this way, cmake's FindJNI will take the values in the registry above all other configurations and paths. If you don't delete these keys, it won't select the right JDK and won't build.

It is also important in your env.txt file to list your JDK 12 path first, since cmake will also take the output of calling java -version above the JAVA_HOME environment variable. This isn't what the documentation for FindJNI says or how it should behave, but that is what it does on Windows. The easiest way of doing this is something like the following:

JAVA_HOME=C:\Program Files\Zulu\zulu-12

in your env.txt. You'll need to expand those manually for that file, so just use the above as a reference for structure.

Once all of the above is setup, you should have all of the dependencies necessary to build:

gradlew clean build
