[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
distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
# distributionUrl=https\://services.gradle.org/distributions/gradle-8.3-all.zip
distributionUrl=https\://mirrors.cloud.tencent.com/gradle/gradle-8.3-all.zip

我任意抓去一个链接访问看看，比如这个
https://maven.aliyun.com/nexus/content/repositories/google/androidx/lifecycle/lifecycle-common/2.7.0/lifecycle-common-2.7.0.pom 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

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