Java 找不到android.arch.lifecycle:compailer:1.1.1错误

我正在尝试在android studio中创建一个房间数据库。但当我构建项目时，我发现找不到android.arch.lifecycle:compailer:1.1.1这个错误

我的gradle版本是3.4.1 android studio版本是3.4.1 我使用java作为编程语言。 谁能帮帮我吗

我在网上搜索了这个错误，但什么也没找到

" 我的gradle文件： 应用插件：“com.android.application”

android {
compileSdkVersion 28
defaultConfig {
    applicationId "com.company.archroomdatabase"
    minSdkVersion 15
    targetSdkVersion 28
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner 
"android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android- 
 optimize.txt'), 'proguard-rules.pro'
    }
 }
 }

dependencies {
def lifecycle_version = "1.1.1"
def room_version = "1.1.1"

annotationProcessor "android.arch.lifecycle:compailer:$lifecycle_version"

//Room components
implementation "android.arch.persistence.room:runtime:$room_version"
annotationProcessor "android.arch.persistence.room:compiler:$room_version"}

我的gradle项目文件：

buildscript {
repositories {
    google()
    jcenter()
    maven { url 'http://repo1.maven.org/maven2' }
    maven {
        url "https://maven.google.com"
    }

}
dependencies {
    classpath 'com.android.tools.build:gradle:3.4.1'

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

allprojects {
repositories {
    google()
    jcenter()

}
}

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

这就是错误：

找不到android.arch.lifecycle:compailer:1.1.1

在以下位置搜索： - - - -

要求：

---

project:app

你拼错了，不是吗

annotationProcessor "android.arch.lifecycle:compailer:$lifecycle_version"

它是

annotationProcessor "android.arch.lifecycle:compiler:$lifecycle_version"
