Could not resolve com.android.tools.build:gradle:8.2.2

Question

I am following the steps on https://learn.microsoft.com/en-us/azure/devops/pipelines/ecosystems/android?view=azure-devops

I have created a pipeline, requested an increase to free parallelism in Azure DevOps which was approved, created a Wear OS app on my local machine, and am trying to build it in the pipeline. However, the pipeline is failing with the below message

Could not resolve all files for configuration ':classpath'.
   > Could not resolve com.android.tools.build:gradle:8.2.2.
     Required by:
         project : > com.android.application:com.android.application.gradle.plugin:8.2.2

The consumer was configured to find a library for use during runtime, compatible with Java 8, packaged as a jar, and its dependencies declared externally, as well as attribute 'org.gradle.plugin.api-version' with value '8.2' but:

My pipeline file is quite simple:

# Android
# Build your Android project with Gradle.
# Add steps that test, sign, and distribute the APK, save build artifacts, and more:
# https://docs.microsoft.com/azure/devops/pipelines/languages/android

trigger:
- master

pool:
  vmImage: 'macos-latest'

steps:
- task: Gradle@2
  inputs:
    workingDirectory: ''
    gradleWrapperFile: 'gradlew'
    gradleOptions: '-Xmx3072m'
    publishJUnitResults: false
    testResultsFiles: '**/TEST-*.xml'
    tasks: 'assembleDebug'

Any idea how to resolve this, besides downgrading my project gradle plugin version?

Answer 1

• Incompatible because this component declares a component for use during compile-time, compatible with Java 11 and the consumer needed a component for use during runtime, compatible with Java 8

Based on the error message, the com.android.tools.build:gradle:8.2.2 requires java 11 or later version.

We can set the argument: jdkVersionOption: '1.17' in Gradle@2 task.

For example:

- task: Gradle@2
  inputs:
    workingDirectory: ''
    gradleWrapperFile: 'gradlew'
    gradleOptions: '-Xmx3072m'
    javaHomeOption: 'JDKVersion'
    jdkVersionOption: '1.17'
    jdkArchitectureOption: 'x64'
    publishJUnitResults: true
    testResultsFiles: '**/TEST-*.xml'
    tasks: 'assembleDebug'
  displayName: gradlew assembleDebug test

Could not resolve com.android.tools.build:gradle:8.2.2.

Based on the old error message, it seems that the gradle:8.2.2 is not able to be found from the resource set in the project.

To solve this issue, you can add the google() to the repositories in build.gradle file.

For example：

buildscript {
    repositories {
        jcenter()
        mavenCentral()
        google() 
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:8.2.2'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}
