尝试在Flutter项目中构建Android应用程序时，我遇到以下错误

What went wrong:

发布规范.yaml文件

flutter_stripe:

安卓/build.gradle文件

buildscript {
    ext.kotlin_version = '1.6.10'
    repositories {
        google()
        mavenCentral()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:4.2.1'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        classpath 'com.google.gms:google-services:4.3.10'
    }
}

allprojects {
    repositories {
        google()
        mavenCentral()
    }
}

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

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

我认为问题与jcentre()有关，但在我的应用程序中没有使用jcentre()，或者stripe也没有使用它，但我仍然得到错误。
构建只是一次又一次地重试，但总是出现相同的错误。
我试过这条线，但没有运气
