Google App引擎端點版本遷移V1到V2

Question

我們已經使用android studio創建了Google Endpoint api v1。 我們收到來自Google雲端的電子郵件，即Google Api v1已被棄用。所以我們嘗試將v1更新爲v2。 所以引用下面的鏈接進行遷移。 https://cloud.google.com/endpoints/docs/frameworks/legacy/v1/java/migrating-android#before_you_begin

變化，當我們試圖運行時演出結束後「... /後端/建設/爆炸-應用」不存在

如果我看看目錄樹我的項目 內我可以看到根據包含Discovery文檔的模塊名稱「backend」和「endpointsDiscoveryDocs」展開目錄「../build/exploded-backend」。

不可用 '... /後端/建設/爆炸-應用' 和 '... /後端/建設/ endpointsClientLibs'

，當我試圖執行，構建成功，但顯示在 錯誤運行後臺：無法啓動的過程中，工作目錄「... \ MyAppliaiton \後端\建立\爆炸，應用」不存在

下面的build.xml在我的Android項目中使用

所有MyApplication的build.gradle

buildscript { 
    repositories { 
     jcenter() 
    } 
    dependencies { 

     classpath 'com.google.guava:guava:19.0' 
     classpath 'com.android.tools.build:gradle:2.3.3' 
    } 
} 

allprojects { 
    repositories { 
     jcenter() 
    } 
} 

task clean(type: Delete) { 
    delete rootProject.buildDir 
} 

應用的build.gradle

**apply plugin: 'com.android.application' 

// V2: Apply the new Endpoints Framework client plugin 
apply plugin: 'com.google.cloud.tools.endpoints-framework-client' 

buildscript { 
    repositories {

     classpath 'com.google.cloud.tools:endpoints-framework-gradle-plugin:1.0.0' 
    } 
}

後端的build.gradle

**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' 


// V2: Apply new App Engine and Endpoints Framework server plugins 
apply plugin: 'com.google.cloud.tools.appengine' 
apply plugin: 'com.google.cloud.tools.endpoints-framework-server' 

dependencies { 

    //appengineSdk 'com.google.appengine:appengine-java-sdk:1.9.42' 

    // V2: Endpoints Framework v2 migration 
    compile 'com.google.endpoints:endpoints-framework:2.0.7' 

    compile 'javax.inject:javax.inject:1' 
    compile 'javax.servlet:servlet-api:2.5'

}

// with the appengine closure 
appengine { // App Engine tasks configuration 


    deploy { // deploy configuration 

     // The following is used for acceptance tests and 
     // is not required for a migration. 
     project = findProperty("appengine.deploy.project") 
     version = findProperty("appengine.deploy.version") 
     def promoteProp = findProperty("appengine.deploy.promote") 
     if (promoteProp != null) { 
      promote = new Boolean(promoteProp) 
     } 
    }

後端的web.xml

**<?xml version="1.0" encoding="utf-8"?> 
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"> 
    <servlet> 
     <servlet-name>EndpointsServlet</servlet-name>

我需要幫助這裏發生了什麼。

Answer 1

我正在更新我的appengine模塊，從Java 7到Java 8和Endpoints v1到Endpoints v2，這確實是一個痛苦的屁股。

我已經解決了它要

[後端模塊]/[後端模塊] .iml

並且改變線路

值=「C： \ workspace \ [project] \ [backend-module] \ build \ exploded-app

到

值=「C：\工作區\ [項目] \ [後端模塊] \建立\ exploded- [後端模塊]
