我试图通过Jenkins构建Android项目，但失败了。同样的构建是工作几天前，我没有在库中做任何更改。以下是相同的控制台日志：

我在浏览器中检查访问https://jcenter.bintray.com/androidx/camera/camera-core/maven-metadata.xml，但我得到以下响应：

{
"errors" : [ {
"status" : 404,
"message" : "Maven metadata not found for 'androidx/camera/camera-core/maven-metadata.xml'."
} ]

下面是我的项目级gradle文件：

buildscript {
repositories {
    google()
    jcenter()

}
dependencies {
    classpath 'com.android.tools.build:gradle:3.6.4'
    classpath 'com.google.gms:google-services:4.3.4'
    classpath 'com.google.firebase:firebase-crashlytics-gradle:2.4.1'
    classpath 'com.google.firebase:perf-plugin:1.3.3'  // Performance Monitoring plugin

}
}

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

应用级gradle文件：

android {
   compileSdkVersion 29
   buildToolsVersion "29.0.3"

defaultConfig {
    applicationId "com.a.b.c"
    minSdkVersion 21
    targetSdkVersion 29
    versionCode 385
    versionName "0.55.2"
    testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    vectorDrawables.useSupportLibrary = true
}

网址：gradle.properties

distributionUrl=https\://services.gradle.org/distributions/gradle-6.1.1-bin.zip

我不能移动到更高的gradle版本，这将迫使升级我的所有库，我不能设置目标版本超过29（它需要大的变化移动到31）
在这里需要建议
