我嘗試將使用 JDO 的谷歌云項目從端點 v1 遷移到 v2。我已經按照遷移指南和這里的一些解決方案嘗試使 datanucleous 插件增強我的類，并將它們上傳到谷歌云，但沒有運氣。我將發布 build.gradle，然后是客戶端嘗試連接到端點時返回的服務器錯誤，這是一個 NoClassFound 錯誤。構建.gradle：buildscript {    repositories {        mavenCentral()        mavenLocal()    }    dependencies {        // App Engine Gradle plugin        classpath 'com.google.cloud.tools:appengine-gradle-plugin:1.3.3'        // Endpoints Frameworks Gradle plugin        classpath 'com.google.cloud.tools:endpoints-framework-gradle-plugin:1.0.2'    }}repositories {    mavenCentral();    jcenter()}apply plugin: 'java'apply plugin: 'war'// [START apply_plugins]apply plugin: 'com.google.cloud.tools.appengine'apply plugin: 'com.google.cloud.tools.endpoints-framework-server'// [END apply_plugins]dependencies {    compile ('com.google.endpoints:endpoints-framework:2.0.8') {        exclude group: 'com.google.guava', module: 'guava-jdk5'    }    compile 'javax.servlet:servlet-api:2.5'    compile 'com.ganyo:gcm-server:1.0.2'    compile 'javax.jdo:jdo-api:3.0.1'    compile 'org.datanucleus:datanucleus-core:3.1.3'    compile 'org.datanucleus:datanucleus-api-jdo:3.1.3'    compile 'org.datanucleus:datanucleus-accessplatform-jdo-rdbms:4.1.1'    compile 'com.google.appengine.orm:datanucleus-appengine:2.1.2'    compile 'com.google.code.gson:gson:2.2.4'    compile 'org.apache.commons:commons-lang3:3.5'}sourceCompatibility = JavaVersion.VERSION_1_7targetCompatibility = JavaVersion.VERSION_1_7appengine {  // App Engine tasks configuration    deploy {   // deploy configuration        version = findProperty("appengine.deploy.version")        def promoteProp = findProperty("appengine.deploy.promote")        if (promoteProp != null) {            promote = new Boolean(promoteProp)        }    }}endpointsServer {    // Endpoints Framework Plugin server-side configuration    hostname = "komilibro.appspot.com"}
