后端模块中的Firebase Admin触发器；所有firebase库必须高于或低于14.0.0

我有一个android studio项目，其中包括一个应用程序模块和一个后端模块

根据文档，我可以使用以下代码将所有构建端点库带到我的应用程序模块：

endpointsServer project(path: ':backend', configuration: 'endpoints')

在我的后端模块gradle中：

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.google.cloud.tools:endpoints-framework-gradle-plugin:1.0.3'
        classpath 'com.google.cloud.tools:appengine-gradle-plugin:1.3.5'
    }

}

repositories {
    jcenter(); }

apply plugin: 'java' apply plugin: 'war'

问题是gradle执行时会导致以下错误：

所有firebase库必须高于或低于14.0.0

我已经看过：

和

但他们都试图在客户端添加AdminSDK。这不是我为什么要这么做的原因

那么，我如何才能告诉gradle这是两个不同的模块，或者在我使用以下模块时，如何排除admin sdk进入我的应用程序模块：

endpointsServer project(path: ':backend', configuration: 'endpoints')

---

目前我找到的唯一方法是删除

endpointsServer项目（路径：':backend'，配置：'endpoints'）

并将我的应用程序项目中的所有clientlib作为jar手动导入，但这是非常低效的：（请编辑您的问题，以显示两个模块的整个最小build.gradle文件。我已经编辑了代码。谢谢！我对这个Google Cloud Endpoints产品了解不够，无法了解它对您的构建所做的工作。请尝试运行

/gradlew:app:dependencies

，以了解在您的build.Als中有哪些不符合标准的库o、 google.gms:google服务的buildscript类路径在哪里？似乎您需要它才能使用google服务插件，它是生成消息的东西。
