Android Plugin for Gradle 3.0.0: Could Not Find com.google.http-client:google-http-client-parent:1.24.1
Introduction
The error “Could not find com.google.http-client:google-http-client-parent:1.24.1” often arises when using Android Plugin for Gradle 3.0.0 or later. This error indicates that the Gradle build system is unable to locate the specified dependency in your project’s repositories.
Understanding the Error
* The error message points to a missing dependency: **com.google.http-client:google-http-client-parent:1.24.1**. This dependency is typically required by libraries that interact with Google APIs or services.
* **google-http-client-parent** is a parent POM (Project Object Model) for the Google HTTP Client library. It provides common configurations and dependencies for other modules within the Google HTTP Client project.
* The version **1.24.1** refers to a specific version of this parent POM.
Causes of the Error
* **Incorrect Dependency Declaration:** The dependency declaration in your **build.gradle** file might contain errors, such as a wrong group ID, artifact ID, or version.
* **Missing Repositories:** The repositories specified in your **build.gradle** file might not include the repository where this dependency is hosted.
* **Dependency Conflicts:** Other dependencies in your project might be incompatible with the required version of **google-http-client-parent**.
* **Outdated Gradle Wrapper:** The Gradle wrapper version used by your project might be outdated and unable to resolve the dependency.
Troubleshooting Steps
1. Verify Dependency Declaration
* **Check for typos:** Ensure that the group ID, artifact ID, and version are correct in your **build.gradle** file.
“`gradle
dependencies {
implementation ‘com.google.http-client:google-http-client-parent:1.24.1’
}
“`
2. Add Missing Repository
* If the dependency is not hosted in your current repositories, add the Google Maven repository to your **build.gradle** file:
“`gradle
repositories {
google()
mavenCentral()
}
“`
3. Resolve Dependency Conflicts
* **Use exclusion:** If the dependency conflict involves a library you cannot remove, you can exclude specific dependencies using the **exclude** keyword.
“`gradle
dependencies {
implementation(‘com.example:library:1.0.0’) {
exclude group: ‘com.google.http-client’, module: ‘google-http-client-parent’
}
}
“`
4. Update Gradle Wrapper
* Check if you are using the latest version of Gradle wrapper by running `gradle wrapper –gradle-version
5. Clean and Rebuild
* After making any changes to your **build.gradle** file, clean and rebuild your project to ensure the changes are applied.
“`bash
./gradlew clean
./gradlew build
“`
