Java克隆人: NoClassDefFoundError

Question

我有一个按钮事件，我尝试用Rits克隆库克隆一个模型。我所做的是：

lodgingForm.getAddButton().setOnAction(event -> addLodging());

和addLodging：

private void addLodging() {
    Cloner cloner = new Cloner();
    Lodging lodging = cloner.deepClone(lodgingForm.getLodging());
    //Add Lodging to an observable list
}

运行这段代码会得到一个NoClassDefFoundError，下面是堆栈：

我看不出我的代码中的错误在哪里？

在Rits项目的GitHub页面上有一个非常密切相关的open issue。我建议您在那里包含您的发现，并与其他贡献者一起工作。
