Question

我在尝试构建项目时遇到此错误。我不知道它有什么问题，我尝试的任何工作都没有。

我正在尝试清理，重新启动Android Studio，并使用gradlew -stop停止守护程序。

请帮助我！

错误：

Android Gradle plugin 3.0.1 must not be applied to project since version 3.0.1 was already applied to this project

模块：应用脚本

apply plugin: 'com.android.application'

android {
    compileSdkVersion 26
    apply plugin: 'com.android.library'

    defaultConfig {

}

项目脚本

    // Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {

    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.1'


        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        google()
        jcenter()
    }

Answer 1

如果您只是创建应用，请删除apply plugin: 'com.android.library'。

如果您要创建一个库，请将apply plugin: 'com.android.application'替换为apply plugin: 'com.android.library'并删除applicationId。

Answer 2

我的问题更加愚蠢。在查找和替换时，我已将versionCode更新为十进制值。

旧值：

versionCode 253 versionName '2.53'

新值：

versionCode 2.54 versionName '2.54'

versionCode的2.54导致了该问题。将其改回254对我来说很成功！
