Apache Pivot - 序列化启动应用程序时的异常



我开始尝试Apache Pivot，因为我想用XML创建java GUI。

我按照他们的Hello BXML教程在他们的网站上使用maven项目。

这些是我正在使用的文件：

你好BXML

.java 
package za.co.iriesoft;
import org.apache.pivot.beans.BXMLSerializer;
import org.apache.pivot.collections.Map;
import org.apache.pivot.wtk.Application;
import org.apache.pivot.wtk.Display;
import org.apache.pivot.wtk.Window;
public class HelloBXML implements Application {
    private Window window = null;
    public void startup(Display display, Map<String, String> properties) throws Exception {
        BXMLSerializer bxmlSerializer = new BXMLSerializer();
        window = (Window) bxmlSerializer.readObject(HelloBXML.class, "hello.bxml");
        window.open(display);
    }
    public boolean shutdown(boolean optional) {
        if (window != null) {
            window.close();
        }
        return false;
    }
    public void suspend() {
    }
    public void resume() {
    }
}

你好.bxml

<?xml version="1.0" encoding="UTF-8"?>
<Window title="Hello BXML!" maximized="true"
    xmlns:bxml="http://pivot.apache.org/bxml"
    xmlns="org.apache.pivot.wtk">
    <Label text="Hello BXML!"
        styles="{font:'Arial bold 24', color:'#ff0000',
            horizontalAlignment:'center', verticalAlignment:'center'}"/>
</Window>

应用.java

package za.co.iriesoft;
import org.apache.pivot.wtk.DesktopApplicationContext;
public class App {
    public static void main(String[] args) {
        DesktopApplicationContext.main(HelloBXML.class, args);
    }
}

当我运行应用程序时，出现异常：

有谁知道可能是什么问题？我整天都在努力尝试不同的IDE，并在Google及其错误数据库中搜索答案，但无济于事。

我正在运行Windows 10，Java SDK 1.8.0_152

我猜你没有"pivot-wtk-terra...类路径中的 jar"文件。 潜在的错误似乎是"找不到主题"。 这个主题是这个"...泰拉...jar"文件。
