[Solved] Gradle compile dependency is not added to classpath

If you’ve encountered the error “Gradle compile dependency is not added to classpath” while working on your Android project, you’re not alone. One common scenario is when adding the Reflections framework to an Android project, and despite your efforts, it doesn’t get added to the classpath automatically.

The suggested solution from Android Studio is to add the dependency manually. However, this can lead to further complications, and in some cases, Gradle might fail to build the app. Let’s delve into a step-by-step guide to troubleshoot and resolve this issue.

The Build.gradle of the App Module

Firstly, let’s review the build.gradle file of your app module. Ensure that you have the necessary dependencies properly configured. In particular, pay attention to the inclusion of the Reflections framework:

            
                // ... (Previous configurations)

                dependencies {
                    // ... (Previous dependencies)

                    compile('org.reflections:reflections:0.9.10') {
                        exclude module: 'xml-apis'
                        exclude module: 'annotations'
                    }

                    // ... (Remaining dependencies)
                }
            
        

Make sure that the Reflections framework is included correctly and that there are no typos or syntax errors.

Project-level Build.gradle

Next, inspect the project-level build.gradle file to guarantee that the necessary repositories are specified. This is crucial for Gradle to locate and download the required artifacts. Here is an example snippet:

            
                buildscript {
                    repositories {
                        jcenter()
                        mavenCentral()
                        mavenLocal()
                    }
                    dependencies {
                        classpath 'org.reflections:reflections:0.9.10'
                        // ... (Other dependencies)
                    }
                }
            
        

Ensure that the repositories include jcenter(), mavenCentral(), and any other repositories relevant to your project. Additionally, check that the Reflections framework is listed under dependencies in the buildscript section.

Conclusion

By following these steps and ensuring correct configurations in both the app module and project-level build.gradle files, you should be able to resolve the Gradle compile dependency issue. Remember to sync your project with Gradle after making changes to apply the modifications.

Programming can be challenging, but with precise configuration and attention to detail, you can overcome obstacles and keep your Android project running smoothly.
