plugin.json

plugin.json is a mandatory file for each Cura plugin which should be located in the plugin's root directory (where the plugin's __init__.py is). The pseudo-JSON file below illustrates what the content of a plugin.json should look like:

{
    "name": "My Cura Plugin",    # mandatory, name of the plugin
    "author": "me",              # mandatory, author name
    "version": "1.0.0",          # mandatory, version of the plugin
    "api": 4,                    # deprecated, use "supported_sdk_versions" instead
    "supported_sdk_versions": ["2", "3", "8"],  # mandatory, this is a list of Cura SDK versions this plugin supports.
    "description": "Misc Debugging Tools for Cura"  # mandatory, description of the plugin
}

Note that supported_sdk_versions is list of discrete CURA SDK versions the plugin supports. Only the versions specified in the list are considered supported. All other versions are considered NOT supported.
