有谁知道如何解决这个问题？

gradle.properties file:

android.jetifier.blacklist = butterknife.*\\.jar

您需要使用AGP的3.3.0-rc1和Kotlin Gradle插件的1.3.0版本：

buildscript {
    repositories {
        ...
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.3.0-rc01'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:1.3.0"
        classpath 'com.jakewharton:butterknife-gradle-plugin:9.0.0-rc2'
    }
}
