Flutter项目报错：无法解析com.stripe:stripe-android:20.12.+依赖求助

项目此前运行一切正常，今日突然出现如下构建错误。

说明：自身应用未使用jCenter，但支付SDK flutter_stripe依赖jCenter。

解决方法 #

• 升级flutter_stripe到最新版本：新版本的stripe_android已迁移至Maven Central，不再依赖jCenter。修改pubspec.yaml中flutter_stripe的版本号后执行flutter pub get。
• 强制指定依赖仓库：若暂时无法升级SDK，可在android/build.gradle中配置依赖解析规则，强制com.stripe组的依赖从Maven Central拉取：

  dependencyResolutionManagement {
    repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
    repositories {
      google()
      mavenCentral()
      exclusiveContent {
        forRepository {
          maven { url "https://repo1.maven.org/maven2/" }
        }
        filter {
          includeGroup "com.stripe"
        }
      }
    }
  }
  

• 清理Gradle缓存：执行以下命令清除本地缓存并重新拉取依赖：
  • Linux/macOS：./gradlew clean build --refresh-dependencies
  • Windows：gradlew clean build --refresh-dependencies
