NesVentory-Android Build Failed: Troubleshooting Guide

Encountering a build failure in your Android project, like NesVentory-Android, can be frustrating. This guide breaks down a recent build failure, analyzes the error logs, and provides steps to troubleshoot and resolve the issues. Let's dive into the details to get your project back on track.

Understanding the Build Failure

When you encounter a build failure in your Android project, it's crucial to understand what went wrong. In this case, a recent build for NesVentory-Android failed, and the build log provides valuable information to diagnose the problem. Let's break down the log and identify the key issues.

Analyzing the Build Log

At the beginning of the build log, you'll see a series of downloads. These downloads indicate that Gradle, the build automation system, is fetching dependencies required for the project. Dependencies are libraries and tools that your project relies on to function correctly. The log shows various components being downloaded, including:

• Kotlin libraries
• KSP (Kotlin Symbol Processing) plugins
• AndroidX libraries (such as Room, Camera, and WorkManager)
• Google libraries (such as ML Kit and Play Services)
• Accompanist Permissions
• Napier logging library

These downloads are a normal part of the build process. However, if any of these downloads fail, it could lead to a build failure. In this case, all downloads appear to have completed successfully, so we need to look further into the log.

Identifying Compilation Errors

The most critical part of the build log is the section that shows compilation errors. These errors occur when the Kotlin compiler encounters issues in your code that prevent it from generating the final application package. In this specific build failure, several Unresolved reference errors are highlighted. These errors indicate that the compiler couldn't find certain classes or functions referenced in the code.

Here’s a breakdown of the key unresolved references:

• QrCodeScanner in ItemEditScreen.kt
• FilterList in ItemsScreen.kt and MaintenanceTasksScreen.kt
• Schedule, Inventory, Repeat, and TaskAlt in MaintenanceTasksScreen.kt
• FlashOff and FlashOn in BarcodeScannerScreen.kt

Additionally, there's an error in BarcodeScannerScreen.kt related to the Icon function, suggesting an issue with the arguments provided to it.

These errors clearly point to missing dependencies or incorrect imports in your Kotlin code. Let's explore how to troubleshoot and resolve these issues.

Troubleshooting Unresolved References

To effectively address the Unresolved reference errors, follow these steps:

1. Verify Dependencies

Start by ensuring that all the necessary dependencies are declared in your project's build.gradle.kts file (or build.gradle if you're using Groovy). The missing classes and functions often belong to external libraries, so you need to include these libraries as dependencies. Check your dependencies block within the build.gradle.kts file to see if the relevant libraries are included. If not, add them.

For example, if QrCodeScanner belongs to a specific barcode scanning library, make sure that library is listed as a dependency. Similarly, if FilterList is part of a UI library, ensure that the library is included.

dependencies {
    implementation("com.example:qr-code-library:1.0.0") // Example for QrCodeScanner
    implementation("com.example:ui-library:2.0.0") // Example for FilterList
    // Other dependencies
}

Remember to replace `
