Introduction

Gradle is a popular build tool used by developers to automate the compilation, testing, and packaging of software projects. However, as new versions of Gradle are released, it's essential to upgrade your project to take advantage of the latest features and improvements. In this article, we'll guide you through the process of upgrading Gradle from version 4.1.3 to 8.1.4, and from version 6.5 to 8.0, while also covering the necessary changes to make your project compatible with the new version.

Understanding the Upgrade Process

Before we dive into the upgrade process, it's essential to understand the changes that have been made in the new version of Gradle. The upgrade from version 4.1.3 to 8.1.4 and from version 6.5 to 8.0 involves several significant changes, including:

  • New build API: The new version of Gradle introduces a new build API that provides a more flexible and efficient way of building projects.
  • Improved dependency management: The new version of Gradle includes improved dependency management features, such as the ability to manage transitive dependencies.
  • Enhanced performance: The new version of Gradle includes several performance improvements, including faster build times and improved memory usage.

Step 1: Update Gradle Version in build.gradle

To upgrade Gradle, you'll need to update the version of Gradle in your build.gradle file. Here's an example of how to update the version of Gradle from 4.1.3 to 8.1.4:

// Before
buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:4.1.3'
    }
}

// After
buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:8.1.4'
    }
}

Similarly, to update the version of Gradle from 6.5 to 8.0, you'll need to update the version of Gradle in your build.gradle file as follows:

// Before
buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:6.5'
    }
}

// After
buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:8.0'
    }
}

Step 2: Update Gradle Version in settings.gradle

In addition to updating the version of Gradle in your build.gradle file, you'll also need to update the version of Gradle in your settings.gradle file. Here's an example of how to update the version of Gradle from 4.1.3 to 8.1.4:

// Before
dependencyResolutionManagement {
    repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
    repositories {
        google()
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:4.1.3'
    }
}

// After
dependencyResolutionManagement {
    repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
    repositories {
        google()
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:8.1.4'
    }
}

Similarly, to update the version of Gradle from 6.5 to 8.0, you'll need to update the version of Gradle in your settings.gradle file as follows:

// Before
dependencyResolutionManagement {
    repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
    repositories {
        google()
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:6.5'
    }
}

// After
dependencyResolutionManagement {
    repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
    repositories {
        google()
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:8.0'
    }
}

Step 3: Update Gradle Version in gradle-wrapper.properties

In addition to updating the version of Gradle in your build.gradle and settings.gradle files, you'll also need to update the version of Gradle in your gradle-wrapper.properties file. Here's an example of how to update the version of Gradle from 4.1.3 to 8.1.4:

distributionBase=GRADLE_HOME
distributionPath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-8.1.4-all.zip
distributionUrl=https\://services.gradle.org/distributions/gradle-8.1.4-all.zip

Similarly, to update the version of Gradle from 6.5 to 8.0, you'll need to update the version of Gradle in your gradle-wrapper.properties file as follows:

distributionBase=GRADLE_HOME
distributionPath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-8.0-all.zip
distributionUrl=https\://services.gradle.org/distributions/gradle-8.0-all.zip

Step 4: Run Gradle Tasks

Once you've updated the version of Gradle in your build.gradle, settings.gradle, and gradle-wrapper.properties files, you'll need to run Gradle tasks to ensure that your project is compatible with the new version of Gradle. Here are some common Gradle tasks that you may need to run:

  • gradle build: This task builds your project and checks for any errors.
  • gradle clean: This task cleans your project and removes any temporary files.
  • gradle test: This task runs your unit tests and checks for any errors.
  • gradle assemble: This task assembles your project and creates a deployable artifact.

Conclusion

Upgrading Gradle from version 4.1.3 to 8.1.4 and from version 6.5 to 8.0 requires several steps, including updating the version of Gradle in your build.gradle, settings.gradle, and gradle-wrapper.properties files, and running Gradle tasks to ensure that your project is compatible with the new version of Gradle. By following the steps outlined in this article, you can ensure a smooth upgrade process and take advantage of the latest features and improvements in Gradle.
