I've cloned the IJ CE source in order to apply some changes to the markdown plugin. The raw clone builds and so does the plugin via Build Project and Build Module respectively.
However, I'm unclear on how to prepare a new standalone zip of my plugin for sharing with other users. There's plenty of advice on how to start a new plugin (https://github.com/JetBrains/intellij-platform-plugin-template) and explanation on why we should use gradle (https://github.com/JetBrains/gradle-intellij-plugin) but nothing I can find tells me how to prepare a release of just markdown functionality. My IJ also does not present the option shown in https://plugins.jetbrains.com/docs/intellij/deploying-plugin.html to "Prepare Plugin Module .. for Deployment".
Can anybody provide some helpful hints?
