Declare a bundled plugin as a dependency in IntelliJ IDEA Plugin - intellij-plugin

Question

Non bundled plugins are stored in the repository and can be referenced by groupId:artifactId:versionId but the documentation only says this ambiguous thing about declaring dependencies on bundled plugins:
locate the plugin’s main JAR file containing META-INF/plugin.xml
descriptor with tag (or if not specified).
Okay. Locate it and do what exactly?

Answer 1

My solution was to copy the template for a gradle IntelliJ plugin and copy this example which led me to declare the dependency by plugin name with no version, groupId. In my case I wanted to use classes from the built-in maven plugin so I added this to the plugins = [....]. The plugin will automatically grab the version of that plugin that is in your IntelliJ.
build.gradle
plugins {
id 'java'
id 'org.jetbrains.intellij' version '0.4.26'
}
group 'com.whatever'
version '1.0-SNAPSHOT'
id 'MyPlugin'
repositories {
mavenCentral()
}
dependencies {
testCompile group: 'junit', name: 'junit', version: '4.12'
runtime files('maven.jar', 'libs/gson-2.2.4.jar')
runtime fileTree(dir: 'libs', include: '*.jar')
}
// See https://github.com/JetBrains/gradle-intellij-plugin/
intellij {
version '2020.2.2'
plugins = ['maven']
}
patchPluginXml {
