android - 无法增强数据核心

Question

将gradle更新为1.0.1之后，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
看来enhacerApi已被弃用，但是我不确定如何解决。

App Engine SDK root = C:\Users\steve.gradle\appengine-sdk\appengine-java-sdk-1.9.17 Java classpath = C:\workspace\ShoutBox\gradle\wrapper\gradle-wrapper.jar;C:\Users\steve.gradle\appengine-sdk\appengine-java-sdk-1.9.17\lib\appengine-tools-api.jar Webapp source directory = C:\workspace\ShoutBox\appengine\src\main\webapp Enhancing DataNucleus classes...
Finished enhancing DataNucleus classes.
:appengine:appengineEnhance FAILED
:appengine:appengineEnhance (Thread[main,5,main]) completed. Took 1.043 secs.

FAILURE: Build failed with an exception.

• What went wrong: Execution failed for task ':appengine:appengineEnhance'.

  An error occurred enhancing DataNucleus classes.

• 尝试:
  使用--debug选项运行，以获取更多日志输出。
• 异常是:

在gradle构建文件中添加缺少的api标签可以解决该问题

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