gradle-intellij-plugin | Gradle plugin for building plugins for IntelliJ-based IDEs | Plugin library

Building for IDEA 2019.1 works like a charm! I thought that building for 2020.3 would be just a matter of pointing to 2020.3 installation folder and that's it, but it is not being even close to it.

That's my gradle.build

I am currently learning about writing plugins for IntelliJ IDEs. I am especially interested in developing plugins for CLion. Therefore I would like to add support for c++ to my plugin project.

I read in the documentation how to develop plugins for c++.However the way it is described does not work for me. IntelliJ cannot resolve the dependency I want to add.

1. This part of the documentation explains that plugins may depend on other plugins, and how to add dependencies.

Plugin dependencies

Your plugin may depend on classes from other plugins. In this case, plugins can be either bundled, third-party or even your own. For instructions on how to express the dependencies, refer to Plugin Dependencies.

Your plugin should specify which product or products it will be compatible with (all IntelliJ-based IDEs, CLion only, or some subset). You can do that by declaring module dependencies with the tag in plugin.xml (see Plugin Compatibility with IntelliJ Products).

2. This part of the documentation explains which functionality is in which plugin. Each specific language seems to be a plugin. So developing a plugin which wants to parse c++, will depend on the c++ plugin.

Modules Specific to Functionality More specialized functionality is also delivered via modules and plugins in IntelliJ Platform-based products. For example, the com.intellij.modules.python module supports the Python language-specific functionality. If a plugin uses functionality from this module, such as Python-specific inspections and refactoring, it must declare a dependency on this module.

...

The following table lists(1) modules or built-in plugins that provide specific functionality, and the products that currently ship with them.

According to the table mentioned above I need to add com.intellij.modules.cidr.lang as dependency for c++. However when I add this line to my plugins.xml file the cidr.lang part is not recognized.

3. In this Stackoverflow question, which is about java plugin development, someone answered that there was recently a change, that one now also has to add the needed plugins to build.gradle. Furthermore there was a change tha java language support is now a buildin plugin.

I guess c++ support is now also a buildin plugin? But how can I add it?

So instead of
