加载默认皮肤创建文本字段和按钮时出错（LibGDX）

我想在LibGDX中创建一些像textfield和textbutton这样的简单元素，并且要这么做，据说需要加载一个我认为可以确定的皮肤元素的布局和设计。加载默认皮肤创建文本字段和按钮时出错（LibGDX）

Skin skin = new Skin(Gdx.files.internal("uiskin.atlas")); 
    nickNameField = new TextField("Enter nickname: ", skin); 
    playButton = new TextButton("Find match", skin);

然而，在尝试加载default skins像uiskin.json和uiskin.atlas，我得到的错误：

任何人都知道的原因呢？
