Android Gradle构建报错求助：插件找不到与版本兼容问题

初始问题 #

遇到无法理解的Gradle构建错误，尝试多种方法未果。初始错误提示：

Could not find com.android.tools.build:gradle:7.6.
Searched in the following locations:
  - https://dl.google.com/dl/android/maven2/com/android/tools/build/gradle/7.6/gradle-7.6.pom
  - https://repo.maven.apache.org/maven2/com/android/tools/build/gradle/7.6/gradle-7.6.pom
Required by:
    project :
Add google Maven repository and sync project
Open File

怀疑问题出在Java版本或build.gradle配置上，当前使用Java JDK 19。

初始配置文件 #

根目录build.gradle：

// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
    repositories {
        google()
        mavenCentral()
    }
    dependencies {
        def nav_version = "2.3.0"
        classpath 'com.android.tools.build:gradle:7.6'
        classpath "androidx.navigation:navigation-safe-args-gradle-plugin:$nav_version"
        classpath 'com.google.gms:google-services:4.3.10'

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

allprojects {
    repositories {
        google()
        mavenCentral()
        maven {
            url 'https://dl.google.com/android/maven2'
        }
    }
}

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

gradle-wrapper.properties：

distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-7.6-bin.zip
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists

根据Gradle兼容文档，Java 19与Gradle 7.6兼容，不理解为何报错。

更新后的问题 #

尝试调整配置后仍报错，以下是更新后的文件：

更新后的配置文件 #

根目录build.gradle（DrinkServer）：

// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
    repositories {
        google()
        mavenCentral()
    }
    dependencies {
        def nav_version = "2.3.0"
        classpath ("com.android.tools.build:gradle:7.4.2")
        classpath "androidx.navigation:navigation-safe-args-gradle-plugin:$nav_version"
        classpath 'com.google.gms:google-services:4.3.10'

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

allprojects {
    repositories {
        google()

新错误提示 #

The Android Gradle plugin supports only Kotlin Gradle plugin version 1.5.20 and higher.
The following dependencies do not satisfy the required version:
root project 'DrinkServer' -> androidx.navigation:navigation-safe-args-gradle-plugin:2.3.0 -> org.jetbrains.kotlin:kotlin-gradle-plugin:1.3.20

奇怪的是，项目完全使用Java，没有用到Kotlin。

已经花了大量时间，仍未解决，求解决建议。
