遷移到雲端點適用於App Engine的Frameworks 2.0

Question

我目前正在嘗試從Cloud Endpoints 1.0遷移到Cloud Endpoints Frameworks 2.0 。

我已按照此處列出的步驟操作： https ： //cloud.google.com/appengine/docs/java/endpoints/migrating？authuser = 0

在我的build.gradle我已經替換了：

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

有：

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

在web.xml我用EndpointsServlet替換了SystemServiceServlet ，用/_ah/api/*替換了/_ah/spi/* /_ah/api/* 。

但是在編譯時，我收到以下錯誤：

 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

我錯過了什么嗎？

根據@saiyr的要求編輯，這是我的build.gradle文件：

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
    }
}

更新：

現在有一個指南詳細介紹了轉換過程： https ： //github.com/GoogleCloudPlatform/endpoints-framework-gradle-plugin/blob/master/ANDROID_README.md
