[解决]Flutter打包Android是出现FAILURE: Build failed with an exception ...

1.问题出现

本日我更新完flutter以后发现Gradle 从7.3 升级到最低8.0，然后gradle-wrapper.properties 里面升级到8.3了，图片如下

1. distributionBase=GRADLE_USER_HOME
2. distributionPath=wrapper/dists
3. zipStoreBase=GRADLE_USER_HOME
4. zipStorePath=wrapper/dists
5. # distributionUrl=https\://services.gradle.org/distributions/gradle-8.3-all.zip
6. distributionUrl=https\://mirrors.cloud.tencent.com/gradle/gradle-8.3-all.zip

复制代码

然后打包APK时出现一个问题，如下

1. Flutter assets will be downloaded from https://storage.flutter-io.cn. Make sure you trust this source!
2. Launching lib\main.dart on ASUS I003DD in debug mode...
3. Flutter assets will be downloaded from https://storage.flutter-io.cn. Make sure you trust this source!
5. FAILURE: Build failed with an exception.

2.挖掘问题根源

我任意抓去一个链接访问看看，比如这个
 

1. https://maven.aliyun.com/nexus/content/repositories/google/androidx/lifecycle/lifecycle-common/2.7.0/lifecycle-common-2.7.0.pom

复制代码

然后上阿里云的镜像网站搜刮这个工具 lifecycle-common

好家伙，阿里云还没更新2.7版本，最高2.6.1版本，所以我在build.gradle里屏蔽了阿里云，写了腾讯的

1. maven { url 'https://mirrors.tencent.com/nexus/repository/maven-public/' } // 腾讯云仓库
2.         mavenCentral()  

复制代码

3.解决问题

不出意外，这次乐成解决了

4.注意

gradle最小可以8.0开始，8.3换腾讯的源也下载很慢，耐心等待
