React Native构建失败：无法加载JCenter Maven元数据求助

问题详情 #

构建时出现如下报错：

FAILURE: Build failed with an exception.

• 位置：构建文件'/Users/users/Documents/MyProject/Project_Name/node_modules/react-native-create-thumbnail/android/build.gradle'第114行
• 问题：配置':react-native-create-thumbnail'项目时出错

无法从https://jcenter.bintray.com/com/facebook/react/react-native/maven-metadata.xml加载Maven元数据

项目此前运行正常，已知需要移除jcenter()但不清楚具体操作，当前android/build.gradle代码如下：

buildscript {
    ext {
        ext.kotlin_version = '1.6.20'
        ffmpegKitPackage = "audio"
        ffmpegKitPackage = "full-gpl"
        buildToolsVersion = "33.0.2"
        minSdkVersion = 24
        compileSdkVersion = 33
        targetSdkVersion = 33
        googlePlayServicesAuthVersion = "19.2.0"

        if (System.properties['os.arch'] == "aarch64") {
            // For M1 Users we need to use the NDK 24 which added support for aarch64
            ndkVersion = "24.0.8215888"
        } else {
            // Otherwise we default to the side-by-side NDK version from AGP.
            ndkVersion = "21.4.7075529"
        }
    }
    repositories {
        google()
        mavenCentral()
    }
    dependencies {
        classpath("com.android.tools.build:gradle:7.4.2")
        classpath("com.facebook.react:react-native-gradle-plugin")
        classpath("de.undercouch:gradle-download-task:5.0.1")
        classpath("com.google.gms:google-services:4.4.0")
        classpath("org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version")
        classpath("com.google.firebase:firebase-crashlytics-gradle:2.9.9")
    }
}

allprojects {
    repositories {
        mavenLocal()
        maven {
            // All of React Native (JS, Obj-C sources, Android binaries) is installed from npm
            url("$rootDir/../node_modules/react-native/android")
        }
        maven {
            // Android JSC is installed from npm
            url("$rootDir/../node_modules/jsc-android/dist")
        }
        mavenCentral {
            // We don't want to fetch react-native from Maven Central as there are
            // older versions over there.
            content {
                excludeGroup "com.facebook.react"
            }
        }

        google()
        jcenter()
        maven { url 'https://www.jitpack.io' }
        maven { url 'https://maven.google.com' }
    }
}

解决步骤 #

1. 打开项目根目录下的android/build.gradle文件
2. 找到allprojects代码块中的repositories部分，删除其中的jcenter()行
3. 修改后的allprojects部分代码如下：

allprojects {
    repositories {
        mavenLocal()
        maven {
            // All of React Native (JS, Obj-C sources, Android binaries) is installed from npm
            url("$rootDir/../node_modules/react-native/android")
        }
        maven {
            // Android JSC is installed from npm
            url("$rootDir/../node_modules/jsc-android/dist")
        }
        mavenCentral {
            // We don't want to fetch react-native from Maven Central as there are
            // older versions over there.
            content {
                excludeGroup "com.facebook.react"
            }
        }

        google()
        maven { url 'https://www.jitpack.io' }
        maven { url 'https://maven.google.com' }
    }
}

4. 清理并重新构建项目：
   • 进入android目录：cd android
   • 执行清理命令：./gradlew clean
   • 返回项目根目录，重新运行项目：npx react-native run-android

说明：jcenter已停止服务，会导致依赖请求失败，移除后构建会从其他有效仓库（如mavenCentral、google等）拉取依赖。
