引起：org.gradle.api.internal.plugins.PluginApplicationException: 无法应用插件 [id 'dexguard']

如何解决引起：org.gradle.api.internal.plugins.PluginApplicationException: 无法应用插件 [id 'dexguard']

我正在 Android 项目中将 dexguard 从 v8 升级到最新版本 9.0.17。到目前为止，一切正常，但现在我需要你的帮助。

按照教程如何在 Android Studio 中从 v8 升级到 v9 并重建项目后，我收到错误：Caused by: org.gradle.api.internal.plugins.PluginApplicationException: Failed to apply plugin [id ' dexguard']

我不确定发生了什么。我尝试了许多组合来修复它并使其工作，但没有成功。她是我的文件： build.gradle ->

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

buildscript {

    repositories {
        maven {
            url 'http://developer.huawei.com/repo/'
        }

        google() // For Android plugin

        jcenter() // For anything else

       flatDir {
            dirs 'app/libs/dexguard'
        }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:4.0.0'
        classpath 'com.google.gms:google-services:4.3.3'
        //classpath 'io.fabric.tools:gradle:1.31.2'
        classpath 'com.google.firebase:firebase-crashlytics-gradle:2.2.0'
        //classpath 'com.guardsquare.dexguard:dexguard-gradle-plugin:'
        classpath 'com.guardsquare:dexguard-gradle-plugin:9.0.17'

        //HUAWEI
        classpath 'com.huawei.agconnect:agcp:1.4.1.300'

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

allprojects {
    repositories {
        google()
        jcenter()

        maven { url "https://maven.google.com" }
        maven { url "https://jitpack.io" }
        maven { url 'http://developer.huawei.com/repo/' }

        flatDir {
            dirs 'libs'
        }

    }
}

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

和 build.gradle(app) 文件 -> :

apply plugin: 'com.android.application'

//apply plugin: 'com.huawei.agconnect'
if (getGradle().getStartParameter().getTaskRequests().toString().contains("Huawei")) {
    apply plugin: 'com.huawei.agconnect'
    println 'Huawei plugins loading'

} else {
    println 'Google plugins loading'

    apply plugin: 'com.google.firebase.crashlytics'
    apply plugin: 'com.google.gms.google-services'
}

apply plugin: 'dexguard'

这里还有一张图片，显示我将 dexguard 文件添加到 app/libs 文件夹中：

如您所见，我添加了 hms/gms 风味，并且在 v8 中运行良好。您可能知道，由于 v8 版本，我们不得不将 com.android.tools.build:gradle 保留为 3.6，因为它不兼容。我看到 v9 现在支持 4+ 构建版本！

感谢您的帮助！

解决方法

这应该是一个非常简单的更改，您的类路径中列出了错误的插件版本。

改变

classpath 'com.guardsquare:dexguard-gradle-plugin:9.0.17'

到

classpath 'com.guardsquare:dexguard-gradle-plugin:1.0.17'

对于我的项目，我还从 com/ 目录中下载的 zip 文件夹中复制了所有内容（忽略我的版本，我还没有使用 9.0.17）
