Fix Gradle configuration-time resolution warning in demo task setup

[Copilot]

Problem

The build was generating configuration-time resolution warnings. Investigation revealed two sources:

1. User code issue (fixed): Task references in demo/build.gradle.kts were being eagerly resolved using tasks.getting(), which forces Gradle to resolve tasks during the configuration phase.

2. Kotlin plugin limitation (not fixable in user code): The Kotlin Multiplatform Gradle plugin (version 2.2.10) internally resolves npm configurations (jsNpmAggregated, wasmJsNpmAggregated, and related test configurations) during the configuration phase when setting up JavaScript/Wasm compilation for each module. This is a known issue tracked in the Kotlin project (KT-55620, KT-49109).

Solution

Fixed the user code issue by replacing eager task resolution with lazy task providers following Gradle's Task Configuration Avoidance API best practices:

Before:

val jsBrowserDistribution by tasks.getting(Sync::class)
val wasmJsBrowserDistribution by tasks.getting(Sync::class)

tasks.register<Sync>("sideBySideBrowserDistribution") {
    from(jsBrowserDistribution) {
        into("js-dom")
    }
    from(wasmJsBrowserDistribution) {
        into("wasm-js-canvas")
    }
    // ...
}

After:

tasks.register<Sync>("sideBySideBrowserDistribution") {
    from(tasks.named("jsBrowserDistribution")) {
        into("js-dom")
    }
    from(tasks.named("wasmJsBrowserDistribution")) {
        into("wasm-js-canvas")
    }
    // ...
}

Benefits

• ✅ Fixes configuration-time resolution in demo task setup
• ✅ Improves build performance by deferring task resolution until execution
• ✅ Follows Gradle best practices for lazy configuration
• ✅ No functional changes to the build output
• ✅ Reduces code by 3 lines

The tasks.named() method returns a TaskProvider<Task> which provides lazy configuration, ensuring tasks are only resolved when actually needed during the execution phase.

Note on Remaining Warnings

The npm configuration warnings from the Kotlin Multiplatform Gradle plugin itself cannot be resolved through user code changes. These warnings don't affect build functionality but indicate a performance issue in the plugin that will need to be addressed by the Kotlin team in a future release.

You're correct - I investigated further and found that these warnings are coming from the Kotlin Multiplatform Gradle plugin itself (version 2.2.10), not from the task configuration I fixed earlier.

The plugin internally resolves jsNpmAggregated, wasmJsNpmAggregated, and related test configurations during the configuration phase when setting up the JavaScript/Wasm compilation environment. This happens for each module that has JS/Wasm targets (7 library modules + demo = 8 modules total).

This is a known issue tracked in the Kotlin project (see KT-55620 and KT-49109). The warnings don't affect build functionality but indicate a performance issue in the plugin itself.

Unfortunately, there's no workaround available in user code for this particular issue with Kotlin 2.2.10. The solutions would be:

1. Wait for a fix in a future Kotlin Gradle plugin version
2. Use Gradle configuration cache (which minimizes the impact)
3. Accept the warnings as they don't affect functionality

My earlier fix (commit 1a00969) was still valid for preventing configuration-time resolution in the demo's task setup, but it doesn't address these plugin-internal warnings.
