java.lang.VerifyError при использовании WCMUsePojo в простом приложении AEM

Question

Ниже приведена ошибка, которую я получаю, когда делаю mvn clean install проекта. Это простое приложение AEM в AEM 6.1, где я пытаюсь использовать WCMUse.

rException 

Ниже приведен код, в котором я использую WCMUsePojo.

package com.mycompany.myproject.controllers; 
import com.adobe.cq.sightly.WCMUsePojo;; 
public class TestController extends WCMUsePojo{ 

    @Override 
    public void activate() throws Exception { 
     // TODO Auto-generated method stub 
     testMethod(); 
    } 

    void testMethod() 
    { 
     System.out.println("test method"); 
    } 

} 

Если я удаляю расширение WCMUsePojo, ошибок нет, и сборка выполняется нормально.

Вы найдете ниже ПОМ, который я использую:

Answer 1

Это происходит главным образом из-за запутанным убер-банку, который обеспечивает только интерфейсы зависимых классов, в то время как WcmUsePojo является классом, а не интерфейса вы видите это вопрос. Один из способов решить эту проблему - либо получить unbfascated jar для Adobe и использовать его, другой - явно добавить видимые зависимости к вашему pom. Вы можете проверить номер версии и другие данные в консоли пучков. В вашем случае вам понадобится только com.adobe.cq.sightly.cq-wcm-sightly-extension пакет в зависимости от вашего POM
