迁移到适用于 App Engine 的 Cloud Endpoints Frameworks 2.0 [英] Migrating to Cloud Endpoints Frameworks 2.0 for App Engine

问题描述

我目前正在尝试从 Cloud Endpoints 1.0 迁移到 Cloud Endpoints Frameworks 2.0.

我已按照此处列出的步骤操作:https://cloud.google.com/appengine/docs/java/endpoints/migrating?authuser=0

在我的 build.gradle 中，我已经替换了:

编译'com.google.appengine:appengine-endpoints:1.9.42'编译'com.google.appengine:appengine-endpoints-deps:1.9.42'

与:

编译'com.google.endpoints:endpoints-framework:2.0.0-beta.5'编译'javax.inject:javax.inject:1'

在 web.xml 中，我用 EndpointsServlet 和 /_ah/spi/* 替换了 SystemServiceServlet与 /_ah/api/*.

但是在编译时，我收到以下错误:

<块引用>

错误:任务:myapp_backend:appengineEndpointsGetClientLibs"的执行失败.>运行端点命令 get-client-lib 时出错:web.xml must have 1 (found:0) SystemServiceServlet servlet

我错过了什么吗?

按照@saiyr 的要求进行编辑，这是我的 build.gradle 文件:

buildscript {存储库{jcenter()}依赖{类路径 'com.google.appengine:gradle-appengine-plugin:1.9.42'}}存储库{jcenter();}应用插件:'java'应用插件:'战争'应用插件:'appengine'sourceCompatibility = JavaVersion.VERSION_1_7targetCompatibility = JavaVersion.VERSION_1_7依赖{//应用引擎appengineSdk 'com.google.appengine:appengine-java-sdk:1.9.42'编译'javax.servlet:servlet-api:2.5'//云端点编译'com.google.appengine:appengine-endpoints:1.9.42'编译'com.google.appengine:appengine-endpoints-deps:1.9.42'//云端点框架//编译 'com.google.endpoints:endpoints-framework:2.0.0-beta.7'//编译'javax.inject:javax.inject:1'//项目编译文件('src/main/webapp/WEB-INF/lib/gson-2.3.1.jar')编译'com.googlecode.objectify:objectify:5.1.9'编译'com.ganyo:gcm-server:1.0.2'编译com.google.appengine.tools:appengine-gcs-client:0.5"}应用引擎{下载 SDK = 真应用配置{oauth2 = 真}端点{getClientLibsOnBuild = 真getDiscoveryDocsOnBuild = true}}

更新:

现在有一份详细介绍过渡过程的指南: https://github.com/GoogleCloudPlatform/endpoints-framework-gradle-plugin/blob/master/ANDROID_README.md

这里:https://cloud.google.com/endpoints/docs/frameworks/legacy/v1/java/migrating-android

解决方案

新插件现已可用，过渡指南:https://github.com/GoogleCloudPlatform/endpoints-framework-gradle-plugin/blob/master/ANDROID_README.md

(或 https://cloud.google.com/endpoints/docs/frameworks/legacy/v1/java/migrating-android)

不要忘记也遵循迁移指南:https://cloud.google.com/appengine/docs/java/endpoints/migrating?authuser=0

I'm currently trying to migrate from Cloud Endpoints 1.0 to Cloud Endpoints Frameworks 2.0.

I've followed the steps outlined here: https://cloud.google.com/appengine/docs/java/endpoints/migrating?authuser=0

In my build.gradle I've replaced:

compile 'com.google.appengine:appengine-endpoints:1.9.42'
compile 'com.google.appengine:appengine-endpoints-deps:1.9.42'

with:

compile 'com.google.endpoints:endpoints-framework:2.0.0-beta.5'
compile 'javax.inject:javax.inject:1'

And in web.xml I've replaced SystemServiceServlet with EndpointsServlet and /_ah/spi/* with /_ah/api/*.

However on compile, I get the following error:

Error:Execution failed for task ':myapp_backend:appengineEndpointsGetClientLibs'.
> There was an error running endpoints command get-client-lib: web.xml must have 1 (found:0) SystemServiceServlet servlet

Am I missing something?

Edit, as requested by @saiyr, here's my build.gradle file:

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.google.appengine:gradle-appengine-plugin:1.9.42'
    }
}

repositories {
    jcenter();
}

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

sourceCompatibility = JavaVersion.VERSION_1_7
targetCompatibility = JavaVersion.VERSION_1_7

dependencies {
    // AppEngine
    appengineSdk 'com.google.appengine:appengine-java-sdk:1.9.42'
    compile 'javax.servlet:servlet-api:2.5'

    //  Cloud Endpoints
    compile 'com.google.appengine:appengine-endpoints:1.9.42'
    compile 'com.google.appengine:appengine-endpoints-deps:1.9.42'

    // Cloud Endpoints Frameworks
    // compile 'com.google.endpoints:endpoints-framework:2.0.0-beta.7'
    // compile 'javax.inject:javax.inject:1'

    // Project
    compile files('src/main/webapp/WEB-INF/lib/gson-2.3.1.jar')
    compile 'com.googlecode.objectify:objectify:5.1.9'
    compile 'com.ganyo:gcm-server:1.0.2'
    compile 'com.google.appengine.tools:appengine-gcs-client:0.5'
}

appengine {
    downloadSdk = true
    appcfg {
        oauth2 = true
    }
    endpoints {
        getClientLibsOnBuild = true
        getDiscoveryDocsOnBuild = true
    }
}
