使用谷歌端点的NoSuchMethod异常+ JDO

我正在做一个基本的JDO查询来搜索一直运行良好的用户，直到昨天，但知道我得到这个内部异常没有（aparently）没有改变我的代码。它发生在开发和生产服务器上。使用谷歌端点的NoSuchMethod异常+ JDO

的简单查询：

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;

这里是堆栈跟踪：

的NoSuchMethodError意味着使用广口瓶的版本不一致，所以有些罐子出来的与其他人一起 – 2014-09-03 09:21:24

感谢您指出@BillyFrost。我在上面添加了我的build.gradle。我试图找到任何不一致，但什么也没找到 – juanmeanwhile 2014-09-03 10:27:15

在我使用下面的依赖使这个工作结束：

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' 
    }

请使用所有依赖的新版本，你可以找到在http://mvnrepository.com/最新版本

然后，继续关注最新版本并更新您的SDK和所有依赖项。

我面临同样的问题，我从改变客体版本解决它：

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

要：

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