Flutter Android端Gradle构建失败：找不到com.otaliastudios:transcoder:0.9.1

问题描述 #

我在Flutter项目中使用video_compress: 3.1.2依赖，iOS模拟器可正常运行，但Android模拟器启动应用时遭遇Gradle构建失败，提示无法解析com.otaliastudios:transcoder:0.9.1依赖（该依赖由video_compress间接引入）。已尝试在app/build.gradle的dependencies块手动添加implementation("com.otaliastudios:transcoder:0.9.1")，但问题仍未解决。

已尝试的无效操作 #

在app/build.gradle的dependencies块添加依赖：

dependencies {
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
    implementation platform('com.google.firebase:firebase-bom:31.0.2')
    implementation("com.otaliastudios:transcoder:0.9.1") // 手动添加的依赖
}

解决方案 #

• 添加JitPack仓库：com.otaliastudios:transcoder托管在JitPack，默认Gradle配置未包含该仓库。修改项目根目录下的build.gradle（注意不是app模块下的），在allprojects/repositories中加入JitPack：

allprojects {
    repositories {
        google()
        mavenCentral()
        maven { url 'https://jitpack.io' } // 新增这一行
    }
}

• 清理Gradle缓存：缓存可能导致依赖解析异常，执行以下命令彻底清理：

flutter clean
flutter pub get
cd android && ./gradlew clean build --refresh-dependencies

• 强制指定依赖版本：如果上述步骤无效，可在app/build.gradle中添加强制依赖策略，确保Gradle拉取指定版本：

configurations.all {
    resolutionStrategy.force 'com.otaliastudios:transcoder:0.9.1'
}
