环境信息 #

• Java version: 22.0.2 (build 22.0.2+9-70)
• Gradle version: 8.9
• Flutter version: 最新版

问题原因与解决步骤 #

核心原因 #

1. AGP版本未发布：com.android.tools.build:gradle:8.9.0并非官方已发布的稳定版本，AGP版本号与Gradle版本并非完全同步，存在版本兼容匹配要求。
2. 无效版本占位符：Maven仓库不支持latest_version作为依赖版本号，必须指定具体有效版本。

解决步骤 #

1. 修正AGP版本
   将android/build.gradle中的AGP版本替换为当前官方已发布的稳定版（例如8.7.2）：

   classpath 'com.android.tools.build:gradle:8.7.2'
   

   注：Gradle 8.9与AGP 8.7.x版本兼容，无需修改gradle-wrapper.properties中的Gradle版本。

2. 修复Groovy依赖版本
   若groovy-all为间接依赖，可在buildscript的dependencies中添加具体版本的依赖声明：

   classpath 'org.codehaus.groovy:groovy-all:3.0.19'
   

   该版本与Gradle 8.9兼容。

3. 清理缓存并同步项目

   • 执行flutter clean清理Flutter项目缓存
   • 执行./gradlew clean build --refresh-dependencies强制刷新Gradle依赖
   • 重新运行Flutter项目
