Question

我正在尝试使用 flutter 构建 APK 文件，但我收到此错误，尽管 flutter run 工作正常。我尝试了以下没有结果： 1-扑干净。 2-删除src里面的flutter并重新安装 3- pub缓存修复

我收到以下错误：

FAILURE: Build failed with an exception.                                

* Where:
Script 'C:\src\flutter\packages\flutter_tools\gradle\flutter.gradle' line: 904

* What went wrong:
Execution failed for task ':app:compileFlutterBuildRelease'.
> Process 'command 'C:\src\flutter\bin\flutter.bat'' finished with non-zero exit value 1

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

* Get more help at https://help.gradle.org

当我运行 flutter doctor 时，我没有收到任何错误

项目级 build.gradle：

buildscript {
    repositories {
        google()
        jcenter()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:4.0.2'
        classpath 'com.google.gms:google-services:4.3.4'
        /* classpath 'com.google.protobuf:protobuf-gradle-plugin:0.8.12' */
    }
}

allprojects {
    repositories {
        google()
        jcenter()
    }
}

rootProject.buildDir = '../build'
subprojects {
    project.buildDir = "${rootProject.buildDir}/${project.name}"
}
subprojects {
    project.evaluationDependsOn(':app')
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

应用级 build.gradle
