如何修复“java.lang.NoClassDefFoundError：com/android/tools/r8/com/google/common/collect/ImmutableMultiset”错误

Question

将我的 android studio 和 gradle 插件升级到最新版本后，我尝试构建我的项目 apk，但出现此错误“原因：com/android/tools/r8/com/google/common/collect/ImmutableMultiset”，我迷路了，在谷歌搜索中找不到与“ImmutableMultiset”相关的任何内容。有谁能帮帮我吗？

我尝试过无效缓存，但没有解决..

buildscript {
    repositories {
        google()
        jcenter()
        maven {
            url 'https://maven.fabric.io/public'
        }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.4.2'
        classpath 'com.google.gms:google-services:4.3.0'
        classpath 'io.fabric.tools:gradle:1.29.0'

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

allprojects {
    repositories {
        google()
        jcenter()
        maven { url "https://jitpack.io" }
    }
}

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