JitPack URL Routing +Automatically identifies external dependencies belonging to the `com.github.*` group (hosted on JitPack) and routes their `primaryUrl` to `https://jitpack.io` instead of attempting standard Maven Central lookup, preventing sandboxed download failures. + +### 3. High-Performance Optimizations +* **Single-Pass Metadata Indexing**: Scans cached metadata files exactly once on-demand, caching them in an in-memory `$O(1)$` lookup map. +* **Deferred Cryptographic Hashing**: Defers expensive SHA-256 calculation until after candidate files are fully deduplicated and sorted. + +--- + +## Usage + +Apply the plugin to the root project's `build.gradle.kts`: + +```kotlin +plugins { + id("meshtastic.flatpak") +} +``` + +### Running the Generator Task + +Execute the registered custom task to sweep your Gradle local modules cache and generate/overwrite the root `flatpak-sources.json`: + +```bash +./gradlew :generateFlatpakSourcesFromCache +``` + +### Custom Cache Directory + +By default, the task scans the standard Gradle user home caches directory (`~/.gradle/caches/modules-2/files-2.1`).
