YAML plugin not found at runtime on the sandbox

Hello.

I am developing a new plugin which depends on YAML bundled plugin.

I have added the following to the build.gradle file

// See https://github.com/JetBrains/gradle-intellij-plugin/
intellij {
    version '2019.2'
    plugins 'yaml'
}

Now the classes  are found when I am developing the plugin but when I execute in the sandbox I got the following error:

Do I need to add any other configuration to the build.gradle like in de dependencies block ? I have never worked with Gradle before.

Thank you.
