Achieve result of IntelliJ "Choose Sources" Dialog in Gradle

I am building extensions for a Java project (Ghidra) with a fairly complicated system of Gradle files. IntelliJ picks up the dependency jars properly, but every time a `.class` file is opened (e.g. during debugging) IntelliJ presents the banner at the top stating:
`Decompiled .class file, bytecode version: 55.0 (Java 11) Choose Sources... `

`Choose Sources` opens the dialog to select the sources, and the `*-src.zip` that is always right next to the `*.jar` file can be selected to add the sources. This can also be done via the project settings.
When adding the `*-src.zip` via the Project Settings there is an explicit warning: `A Library is imported from Gradle. Any changes made in its configuration might be lost after reimporting.`. This behavior is still the case when using `Choose Sources`, there is just no warning.

### Core question

How do I add the sources to Gradle configuration in a way that IntelliJ (or any other IDE) recognizes automatically? I.e. what is the Gradle directive that achieves what the `Choose Sources` dialog in IntelliJ IDEA does and is applied every time the Gradle project is reloaded?

The way the dependencies are declared in a Gradle file, that is included in the actual `build.gradle`, in this way:

dependencies {
api fileTree(dir: ghidraDir + '/Framework', include: "**/*.jar")
}

### Attempts
My first attempt was to change this to

api fileTree(dir: ghidraDir + '/Framework', includes: ["**/*.jar", "**/*-src.zip"])

But this adds the zip as a separate archive file in IntelliJ, and not as the sources for a dependency jar.

### Gradle code for Eclipse

The Gradle code that seems to achieve the same result for Eclipse looks like the following, specifically the `entry.setSourcePath`

eclipse {
  classpath {
    downloadJavadoc = true
    downloadSources = true
    file {
      whenMerged {
        File javaDoc = new File(ghidraInstallDir+"/docs/GhidraAPI_javadoc.zip");
        for (entry in entries) {
          if (entry.path.contains('jar')) {
            File folder = new File(entry.getPath()).getParentFile();
            for (File file : folder.listFiles()) {
              if (file.getName().endsWith(".zip")) {
                if (file.getName().contains("-src")) {
                  entry.setSourcePath(it.fileReference(file));
                }
              entry.setJavadocPath(it.fileReference(javaDoc));
             }
           }
         }
       }
       entries.add(
         new org.gradle.plugins.ide.eclipse.model.Library(
           it.fileReference(new File(projectDir, '/bin'))
         )
       )
     }
   }
 }
}
