This demo plugin comes with some Gradle tasks to help you with the development of your plugin. In order to use them, it is recommended to use Intellij IDEA as it has been tested with this IDE. However, other programs such as Eclipse may also work, but the procedure may change. In Intellij, find your working folder and open the build.gradle file. Then, load th gradle project and wait. If you don't have a JDK for Java 16, you will need to install one. You can go on Adoptium (AdoptOpenJDK) to find one. When it is done, you should be able to see a new task group called mcreator_plugins in the sidebar "Gradle". Those tasks are:

• exportPlugin: Create a new ZIP archive containing the plugin in a build folder
  • You can edit the name using Globals.ARCHIVE_NAME in the build.gradle file.
• install: Install the plugin (the generated file of exportPlugin) inside the plugins folder of MCreator.
• runMCreator: Export and install the plugin and then, launch MCreator.
  • The default root of each OS is used, but you can customize it by changing one of the following variables in the build.gradle. Globals.MCREATOR_ROOT_FOLDER_WINDOWS and Globals.MCREATOR_ROOT_FOLDER_MAC_LINUX

To export your plugin, you can use the provided Gradle task. Read the section above for more information.

To export the plugin, simply archive the src folder of the plugin into a ZIP file, so the plugin has the following structure:

• <plugin file name>.zip
  • plugin.json
  • (procedures)
  • (<generator 1 name>)
  • ...

To export your plugin, you can use the provided Gradle task. Read the Gradle tasks for more information.

To install exported plugin in MCreator, put the plugin ZIP file into <user home>/.mcreator/plugins or install them from MCreator's preferences window and relaunch MCreator.

Generators are added in the root folder of the plugin:

• <plugin file name>.zip
  • <generator 1 name>
  • <generator 2 name>
  • <generator 3 name>
  • ...

Generator names are formatted like this:

FLAVOR-generatorName

Where FLAVOR can be:

• forge - eg. "forge-1.15.2" - such generators indicate forge generator flavor
• datapack - eg. "datapack-1.14.4" - such generators indicate datapack generator flavor
• addon - eg. "addon-1.14.x" - such generators indicate addon generator flavor
• fabric - eg. "fabric-1.16.1" - such generators indicate fabric generator flavor
• spigot - eg. "spigot-1.16.1" - such generators indicate spigot generator flavor

All files outside the src folder are not part of the plugin structure but are there for the purpose of Intellij IDEA IDE support for better plugin development, documentation purposes and similar.
