React Native项目EAS构建报错：找不到maven插件

执行eas build -p android --profile android-preview构建Android预览版时，出现如下错误：

[stderr] A problem occurred evaluating project ':unimodules-core'.
[stderr] >
[stderr] Plugin with id 'maven' not found.

看到有建议将build.gradle里的apply plugin: 'maven'替换为apply plugin: 'maven-publish'，但在项目根目录的build.gradle中找不到相关引用，当前根build.gradle内容如下：

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    ext {
        buildToolsVersion = findProperty('android.buildToolsVersion') ?: '31.0.0'
        minSdkVersion = Integer.parseInt(findProperty('android.minSdkVersion') ?: '21')
        compileSdkVersion = Integer.parseInt(findProperty('android.compileSdkVersion') ?: '31')
        targetSdkVersion = Integer.parseInt(findProperty('android.targetSdkVersion') ?: '31')
        if (findProperty('android.kotlinVersion')) {
            kotlinVersion = findProperty('android.kotlinVersion')
        }
        frescoVersion = findProperty('expo.frescoVersion') ?: '2.5.0'
        kotlinVersion: '1.6.20'

        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:7.2.1')
        classpath('com.facebook.react:react-native-gradle-plugin')
        classpath('de.undercouch:gradle-download-task:5.0.1')
        classpath('org.jetbrains.kotlin:kotlin-gradle-plugin:1.6.20')
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

def REACT_NATIVE_VERSION = new File(['node', '--print', "JSON.parse(require('fs').readFileSync(require.resolve('react-native/package.json'), 'utf-8')).version"].execute(null, rootDir).text.trim())

allprojects {
    configurations.all {
        resolutionStrategy {
            force "com.facebook.react:react-native:" + REACT_NATIVE_VERSION
        }
    }

    repositories {
        mavenLocal()
        maven {
            // All of React Native (JS, Obj-C sources, Android binaries) is installed from npm
            url(new File(['node', '--print', "require.resolve('react-native/package.json')"].execute(null, rootDir).text.trim(), '../android'))
        }
        maven {
            // Android JSC is installed from npm
            url(new File(['node', '--print', "require.resolve('jsc-android/package.json')"].execute(null, rootDir).text.trim(), '../dist'))
        }

        google()
        mavenCentral {
            // We don't want to fetch react-native from Maven Central as there are
            // older versions over there.
            content {
                excludeGroup 'com.facebook.react'
            }
        }
        maven { url 'https://www.jitpack.io' }
    }
}

解决方案 #

错误出现在:unimodules-core模块，说明问题不在根build.gradle，而是在依赖库的内部配置文件中，按以下步骤修复：

方法1：手动修改依赖库文件 #

1. 找到项目中node_modules/expo-unimodules/unimodules-core/android/build.gradle文件
2. 查找其中的apply plugin: 'maven'代码行
3. 将其替换为apply plugin: 'maven-publish'
4. 重新执行构建命令eas build -p android --profile android-preview

方法2：用patch-package永久修复（推荐） #

避免每次安装依赖后重复手动修改：

1. 安装patch-package：

npm install patch-package --save-dev

2. 完成方法1中的文件修改后，执行命令生成补丁：

npx patch-package expo-unimodules

3. 将生成的patches/expo-unimodules+[对应版本号].patch文件提交到版本控制
4. 后续执行npm install时，patch-package会自动应用这个补丁

方法3：升级依赖版本 #

如果你的expo-unimodules版本较旧，直接升级到最新稳定版，新版本可能已兼容Gradle 7+：

npm install expo-unimodules@latest
