Android Studio找不到Kotlin依赖项

Question

我正在尝试为我的Android Studio项目升级一些依赖项，现在每当我尝试构建项目时，我都会遇到此错误消息：

Could not determine the dependencies of task ':app:compileDebugJavaWithJavac'.
> Could not resolve all task dependencies for configuration ':app:debugAnnotationProcessorClasspath'.
   > Could not find org.jetbrains.kotlin:kotlin-stdlib-jdk8:1.3.60-eap-25.
     Searched in the following locations:
       - https://dl.google.com/dl/android/maven2/org/jetbrains/kotlin/kotlin-stdlib-jdk8/1.3.60-eap-25/kotlin-stdlib-jdk8-1.3.60-eap-25.pom
       - https://jcenter.bintray.com/org/jetbrains/kotlin/kotlin-stdlib-jdk8/1.3.60-eap-25/kotlin-stdlib-jdk8-1.3.60-eap-25.pom
     Required by:
         project :app > androidx.databinding:databinding-compiler:4.0.0-alpha04
         project :app > androidx.databinding:databinding-compiler:4.0.0-alpha04 > androidx.databinding:databinding-compiler-common:4.0.0-alpha04

这是我的项目gradle文件：

buildscript {
    // Define versions in a single place
    ext {
        // Sdk and tools
        compileSdkVersion = 28
        minSdkVersion = 21
        targetSdkVersion = 28

        // App dependencies
        appCompatVersion = '1.1.0'
        fragmentVersion = '1.2.3'
        gradleVersion = '4.0.0-alpha04'
        kotlinVersion = '1.3.60-eap-25'
        ktlintVersion = '0.33.0'
        ktxVersion = '1.2.0'
        mapVersion = '17.0.0'
    }

    repositories {
        google()
        jcenter()
        mavenCentral()
        maven { url 'https://dl.bintray.com/kotlin/kotlin-eap'}
    }

    dependencies {
        classpath "com.android.tools.build:gradle:${gradleVersion}"
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlinVersion"
        classpath "androidx.navigation:navigation-safe-args-gradle-plugin:$navigationVersion"
    }
}

plugins {
    id "com.diffplug.gradle.spotless" version "3.24.0"
}

allprojects {
    repositories {
        google()
        jcenter()
    }
}

spotless {
    kotlin {
        target "**/*.kt"
        ktlint(ktlintVersion).userData(['max_line_length' : '100'])
    }
}

以及相关的应用gradle依赖项：

kaptTest "androidx.databinding:databinding-compiler:$gradleVersion"
implementation "androidx.core:core-ktx:$rootProject.ktxVersion"
implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk8:$rootProject.kotlinVersion"

我尝试使用其他Kotlin版本，但是这样做时甚至无法同步gradle文件。

尝试一下：

build.gradle（：app）
