Question

我正在尝试使用自定义库反射浏览已实现接口的所有类。这是我的来源：

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：

mod.api.core包退出。所以这不应该是错误。

Answer 1

java.lang.NoClassDefFoundError：javassist / bytecode / ClassFile

您可以通过将javassist-3.12.1.GA.jar添加到类路径

来解决此问题
