Can't generate ViewBinding Code

[lalozhang]

`buildscript {
ext.kotlin_version = '1.4.21'

dependencies {
    classpath 'com.android.tools.build:gradle:4.1.2'
    classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    classpath 'com.jakewharton:butterknife-gradle-plugin:10.2.3'
}

}this is my project gradle apply plugin: 'kotlin-android'
apply plugin: 'kotlin-kapt'
apply plugin: 'kotlin-android-extensions'

android {
compileSdkVersion 30
buildToolsVersion "30.0.3"
defaultConfig {
minSdkVersion 16
targetSdkVersion 30
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
kapt {
arguments {
arg("AROUTER_MODULE_NAME", project.getName())
}
}
}

buildFeatures {
    viewBinding true
}

viewBinding {
    enabled = true
}
sourceSets {
    main {
        assets.srcDirs = ['assets']
        jniLibs.srcDirs = ['libs']
    }
}
buildTypes {
    debug {
        // 显示Log
        buildConfigField "boolean", "LOG_DEBUG", "true"
    }
    release {
        // 不显示Log
        buildConfigField "boolean", "LOG_DEBUG", "false"
    }
}
useLibrary 'org.apache.http.legacy'
compileOptions {
    sourceCompatibility = '1.8'
    targetCompatibility = '1.8'
}

kotlinOptions {
    jvmTarget = '1.8'
}

}

def ktxVersion = "2.3.0"

dependencies {
api fileTree(include: ['*.jar'], dir: 'libs')
api 'com.jakewharton:butterknife:10.2.3'
api 'androidx.lifecycle:lifecycle-extensions:2.2.0'
api "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version"
api 'androidx.core:core-ktx:1.3.2'

api "androidx.lifecycle:lifecycle-livedata-ktx:$ktxVersion"
api "androidx.activity:activity-ktx:1.2.2"
api 'androidx.fragment:fragment-ktx:1.3.2'
}`
and this is my base module gradle

`apply plugin: 'com.android.application'
apply plugin: 'org.greenrobot.greendao'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-android-extensions'
apply plugin: 'kotlin-kapt'

android {
compileSdkVersion 30
buildToolsVersion "30.0.3"
defaultConfig {
applicationId "com.nucarf.member"
minSdkVersion rootProject.ext.minSdkVersion
targetSdkVersion 30
}
}

buildFeatures {
    viewBinding true
}

kotlinOptions {
    jvmTarget = '1.8'
}

repositories {
flatDir {
dirs 'libs'
}
}
pendencies {

kapt 'com.jakewharton:butterknife-compiler:10.2.3'

}

this is my app gradle ,app depends on base module .but in my app 's build dir generated/ap_generated_sources,can't generate code
