Java Reflections'NoClassDef'错误

我试图浏览所有使用自定义库文件Reflections实现了一个接口的类。下面是我的源：Java Reflections'NoClassDef'错误

public static List<IModdable> getAllModClasses() { 
    Reflections reflections = new Reflections("mod.api.core"); //getting error here 
    Set<Class<? extends IModdable>> classes = reflections.getSubTypesOf(IModdable.class); 
    List<IModdable> modList = new ArrayList<IModdable>(); 
    for (Class<? extends IModdable> c : classes) 
     try { 
      modList.add((IModdable) c.newInstance()); 
     } catch (Exception ex) { 
      err(String.format("Could not load mod %s !", c.getName())); 
     } 


    return modList; 
}

错误：

的mod.api.core包退出。所以这不应该是错误。

看起来你缺少[javassist-3.12.1.GA解决问题。 jar]（http://jboss-javassist.github.io/javassist/）.. –

工作！回答它给你打勾 –

java.lang.NoClassDefFoundError：Javassist是/字节码/ ClassFile的

您可以通过添加javassist-3.12.1.GA.jar到classpath
