JSON FileType not resolving new 2024.3 plugin

Same here. And also it gives below compile error even though I add com.intellij.modules.json  in plugin.xml.

error: package com.intellij.json does not exist
import com.intellij.json.JsonLexer;

Hi,

Please share Gradle build script files.

Here is build.gradle.kts file.

Hi I have migrated to gradle 2x plugin in my olugin but somehow it is not resolving anything. So I have checked out Intellij Plugin Template and replaced all my files, and it was successful. 

But I changed the 

platformType = IC
platformVersion = 2024.3

and then the JSON module is not resolving. 

This is exactly the same with the template.

Thanks

Since the 2024.3 release cycle, com.intellij.modules.json is a standalone bundled plugin. To load it properly for the compilation time, you need to add it with:

dependencies {
    // …
    intellijPlatform {
        // …
        bundledPlugin("com.intellij.modules.json")
    }
}

or, if using the IntelliJ Platform Plugin Template setup, in gradle.properties:

platformBundledPlugins = com.intellij.modules.json 

Also, we will fix the docs to be more explicit about what is required depending on the target version.
