Question

我是 flutter 新手，我正在尝试运行我的应用程序，并且我得到这个“kotlin-android”插件需要 Android Gradle 插件之一。

这是我尝试运行该应用程序时显示的错误。

失败：构建失败并出现异常。

• 出了什么问题： 配置根项目“android”时出现问题。

'kotlin-android' 插件需要 Android Gradle 插件之一。 请将以下插件之一应用到“：”项目：

• com.android.application
• com.android.library
• com.android.dynamic-feature
• com.android.asset-pack
• com.android.asset-pack-bundle
• com.android.lint
• com.android.test
• com.android.instantapp
• com.android.feature

• 尝试： 使用 --stacktrace 选项运行以获取堆栈跟踪。使用 --info 或 --debug 选项运行以获得更多日志输出。使用 --scan 运行以获得完整的见解。

• 在 https://help.gradle.org

Answer 1

你的build.gradle应该是这样的

buildscript {
ext.kotlin_version = '1.3.50'
repositories {
    google()
    jcenter()
    maven {
        url 'http://storage.googleapis.com/r8-releases/raw'
    }
}

dependencies {
    classpath 'com.android.tools:r8:1.5.25'
    classpath 'com.google.gms:google-services:4.3.2'
    classpath 'com.android.tools.build:gradle:3.5.0'
    classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
  }
}

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
}

如果上述解决方案失败，您可以尝试在settings.gradle中查找kotlin版本
