Problem

The Gradle plugin hardcodes composeApp.js as the script filename in JsSourceGeneratorTask and WasmSourceGeneratorTask. When Storytale is applied to projects using other module names (such as :shared or nested :app:shared), the generated index.html references a non-existent composeApp.js, causing a 404 script loading failure in the browser.

Solution

1. Configurable Script Filename: Added a scriptFileName: Property<String> property to JsSourceGeneratorTask and WasmSourceGeneratorTask, defaulting to composeApp.js for backwards compatibility.
2. Dynamic Script Resolution: Added resolveScriptFileName(target) in the Gradle plugin to resolve the script bundle name dynamically:
   • Webpack task mainOutputFileName (if configured)
   • Kotlin Multiplatform target.outputModuleName
   • Project name fallback (${project.name}.js)
3. Task Grouping: Ensured generated web story run tasks are grouped under storytale.
4. Unit Tests: Added ResolveScriptFileNameTest verifying resolution across:
   • Root application layout (composeApp -> composeApp.js)
   • Library subproject layout (:shared -> shared.js)
   • Nested subproject hierarchy (:app:shared -> root-app-shared.js)
   • Custom outputModuleName override via KGP DSL
   • Webpack task mainOutputFileName override

Verification

• ./gradlew spotlessCheck (passes)
• ./gradlew -p modules/gradle-plugin test (5/5 unit tests pass in ResolveScriptFileNameTest)
• ./gradlew :examples:wasmJsBrowserStoriesDevelopmentRun (verifies existing :examples app)
• ./gradlew :shared:wasmJsBrowserStoriesDevelopmentRun -PcmpProfile=1.10 in aryapreetam/storytale-sample (verifies :shared library module)

Visual Verification & Reproduction Steps

1. Internal Application (:examples)

Run the Wasm development server in the repository(./gradlew :examples:wasmJsBrowserStoriesDevelopmentRun):

2. External KMP Project with :shared module (aryapreetam/storytale-sample)

Reproduction Steps:

1. Publish the updated Gradle plugin locally(from storytale root):

./gradlew publishToMavenLocal

2. Clone storytale-sample (if not already cloned):

git clone https://github.com/aryapreetam/storytale-sample.git
cd storytale-sample

3. In shared/build.gradle.kts, apply the local snapshot:

plugins {
  ...
- id("io.github.aryapreetam.storytale") version "0.0.6"
+ id("org.jetbrains.compose.storytale") version "0.0.4-SNAPSHOT"
}

4. In settings.gradle.kts, set Kotlin to 2.3.10 under profile 1.10 (to match the current compiler plugin baseline):

...
versionCatalogs {
  create("libs") {
    when (profile) {
      "1.10" -> {
-       version("kotlin", "2.3.21")
+       version("kotlin", "2.3.10")
        ...
      }
      ....
    }
  }
}
...

Note: Verified against Kotlin 2.3.10 baseline to match the current compiler plugin registrar. (A separate PR will address IrGenerationExtension compatibility for Kotlin 2.3.20+ / 2.4+).

5. Launch Wasm stories ./gradlew :shared:wasmJsBrowserStoriesDevelopmentRun -PcmpProfile=1.10:
