未能增强数据核心

Question

在将我的gradle更新到1.0.1后，我的appengine构建失败

我得到错误：

groovy.lang.MissingPropertyException: Could not find property 'enhancerApi' on com.google.appengine.AppEnginePluginExtension_Decorated@1dd443c1

看起来enhacerApi已经被弃用了，但我不确定如何解决这个问题。

App Engine SDK root=C:\Users\steve.gradle\aappengine SDK\aappengine-java-SDK-1.9.17Java classpath=C:\workspace\ShoutBox\gradle\wrapper\gradle-wrapper.jar；C： \Users\steve.gradle\appengine sdk\appengine-java-sdk-1.9.17\lib\aappengine-tools-api.jarWebapp源目录=C:\workspace\ShoutBox\appengine\src\main\Webapp正在增强DataNucleus类
已完成对DataNucleus类的增强
：appengine:appengineEnhance失败
：appengine:appengine Enhance(线程[min，5，main])已完成。耗时1.043秒。

失败：生成失败，出现异常。

• 出了什么问题：任务"：appengine:appengineEnhance"执行失败。

  增强DataNucleus类时出错。

• 尝试：
  使用--debug选项运行以获得更多日志输出。

•

Answer 1

在gradle构建文件中添加缺失的api标记解决了问题

enhancer {
version = "v2"
api="jdo"  // or "jpa"
enhanceOnBuild = true
}
