How to configure plugins to run on multiple platforms

IntelliJ Platform
1

How can the plugin run on multiple platforms? Use platform-specific APIs at the same time.

For example, I used PsiMethod on idea, but how can I configure it to run on pycharm?

You need to use optional plugin XML descriptors for different plugins/IDEs

<depends
    optional="true"
    config-file="myPluginId-for-Java.xml">com.intellij.java</depends>

I know this, but how to configure it in the kts script? If I want to run PY, then there can’t be a “com.intellij.java” dependency. I want my plugin to call platform-specific APIs.

intellij {
    version.set("2024.1")
    type.set("IC") // Target IDE Platform
    plugins.set(
        listOf(
            "com.intellij.java",
            "properties",
            "org.jetbrains.plugins.yaml",
            "Kotlin",
            "com.intellij.gradle"
        )
    )

}

I think when the plugin runs on idea, I can use apis such as JavaShortNamesCache, and when it runs on pycharm, I can use apis such as PyFunctionNameIndex

If platform specific code can’t be placed in classes with extension point implementation (instantiating in those platform specific xmls), then I use next trick:
Create factory/proxy through which all such calls happened. And in that factory use reflection to check availability of corresponding platform specific class. If available then invoke/instantiate class with usage of those platform specific code.
