使用google端点+ JDO的NoSuchMethod异常

我正在做一个基本的JDO查询来搜索到昨天工作良好的用户，但是知道我得到了这个内部异常而没有（显然）在我的代码中没有改变任何内容。 它发生在开发和生产服务器上。

简单查询：

PersistenceManager pm = getPersistenceManager();

Query query = pm.newQuery(KomiUser.class);
query.setFilter("email == emailParam");
query.declareParameters("String emailParam");
List<KomiUser> results = (List<KomiUser>) query.execute(email);

if (results != null && results.size() > 0)
      return results.get(0); //should be only one

return null;

这是stacktrace：

最后，我通过使用以下依赖项来完成这项工作：

    dependencies {
        appengineSdk 'com.google.appengine:appengine-java-sdk:1.9.10'
        compile 'com.google.appengine:appengine-endpoints:1.9.10'
        compile 'com.google.appengine:appengine-endpoints-deps:1.9.10'
        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 'com.google.appengine.orm:datanucleus-appengine:2.1.2'
   }

请使用所有依赖项的较新版本，您可以在http://mvnrepository.com/

找到最新版本

然后，继续观看最新版本并更新SDK和所有依赖项。

我遇到了同样的问题，我通过改变Objectify版本解决了这个问题：

compile 'com.googlecode.objectify:objectify:4.0b3'

要：

compile 'com.googlecode.objectify:objectify:5.0.3'
