尝试在 Android Studio 上运行 Enhance [英] Trying to run Enhance on Android Studio

问题描述

我正在尝试在 Android Studio 中设置 jdo/jpa 并遵循了上一个问题的答案 此处.

I'm trying to setup jdo/jpa in Android Studio and havefollowed an answer from a previous question here.

当我尝试运行增强任务时，我得到:

When I attempt to run the enhance task I get:

Error:Execution failed for task ':backend:appengineEnhance'.
An error occurred enhancing DataNucleus classes.

并且日志文件显示:

上周我认为这在我的桌面上运行良好，但我试图在我的笔记本电脑上复制它，但似乎没有任何工作(克隆的 bitbucket 存储库).这是我的毕业证书:

I thought this worked fine last week on my desktop but I'm trying to replicate it on my laptop and nothing appears to be working (cloned bitbucket repository). Here is my gradle:

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.google.appengine:gradle-appengine-plugin:1.9.1'
    }
}

repositories {
    mavenCentral();
}

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

sourceCompatibility = 1.7
targetCompatibility = 1.7

dependencies {
  appengineSdk 'com.google.appengine:appengine-java-sdk:1.9.1'
  compile 'com.google.appengine:appengine-endpoints:1.9.1'
  compile 'com.google.appengine:appengine-endpoints-deps:1.9.1'
  compile 'javax.servlet:servlet-api:2.5'

    // Persistence
    compile 'org.ow2.asm:asm:4.0'
    compile 'org.datanucleus:datanucleus-api-jpa:3.1.3'
    compile 'org.datanucleus:datanucleus-api-jdo:3.1.3'
    compile 'com.google.appengine.orm:datanucleus-appengine:2.1.2'
    compile 'org.datanucleus:datanucleus-core:3.1.3'
    compile 'org.apache.geronimo.specs:geronimo-jpa_2.0_spec:1.0'
    compile 'javax.jdo:jdo-api:3.0.1'
    compile 'javax.transaction:jta:1.1'

}

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

推荐答案

根据上面的@loosebazooka，答案是在上面评论中的链接中使用 v2 增强器.

Per @loosebazooka above the answer is to use the v2 enhancer at the link in the comments above.
