端点客户端库无法识别

Question

不确定发生了什么，但是在移动到 gradle 3.0.0 rc2 之后，我的应用程序模块无法识别端点模块生成的任何客户端库。

构建可以完成 w/o 任何问题，只有一个例外...none 的新 API 被构建选中。

这是我的应用程序模块中 gradle 文件的依赖项部分：

dependencies {
// Gradle dependency check...must be run in the project directory
// ./gradlew -q dependencies app:dependencies --configuration compile

implementation fileTree(include: ['*.jar'], dir: 'libs')
implementation project(path: ':backend', configuration: 'android-endpoints')

更新：

我注意到 war/jar 文件在 backend/build/libs 中不断更新，zip 文件也在 backend/build/client-libs 中更新。

更新#2：

这发生在 Android Studio 3.0 中。

更新#3： 显然，这是 3.0 rc2 的一个已知错误，请参阅 here

更新#4 这是 Google 团队的建议，但我不知道如何让它发挥作用。有人吗？

//In library module:

dependencies {
   api fileTree(include: ['*.jar'], dir: 'libs')
}

Answer 1

这是 Google 截至 2017 年 11 月 1 日的展位：Upgrade the framework to v2。

他们还提供了一些解决方法（您的经理可能不喜欢这样）：

Build the client library manually and copy it over. [Use gradle task : appengineEndpointsGetClientLibs]

Export a pre-built jar and copy it over. [Use gradle task : appengineEndpointsExportClientLibs] NOTE : 2 and 3 will require you to add the google-api-client-lib dependency directly on the android app

Try to use the new plugins that use a different mechanism, while it does automatically add source to your project, this does NOT integrate with Android Studio's UI - so you will have to use gradle/command-line tooling directly for running and deploying: https://github.com/GoogleCloudPlatform/endpoints-framework-gradle-plugin/blob/master/ANDROID_README.md

我已经在问题描述中提供了我的 gradle 文件，以供您参考。

Answer 2

我在过去 10 天里调查了这个问题，这是我所了解的。 Google 关于端点开发的哲学，自第一次引入以来就集成在 Android Studio 中，现在已经发生了变化。事实上，AndroidStudio 3 将不再提供对端点的原生支持（事实上，您不能再添加端点模块）。基本上，他们试图将后端开发（这对所有平台都是通用的）与客户端开发分开。因此，他们会鼓励您在 IntelliJ 上开发后端，然后将生成的库导入您的 'lib' 文件夹（现在是项目创建时的默认文件夹）。他们还为 IntelliJ 提供了专用端点部署工具（参见 https://cloud.google.com/tools/intellij/docs/）。
