Java will compile from command line but not NetBeans

Question

This same Java class will compile from the command line, but not from NetBeans. Here is the .java file contents:

package com.ripplesoftware.sitereviewer;

import com.trolltech.qt.gui.QApplication;
import com.trolltech.qt.core.QTextCodec;
import com.trolltech.qt.gui.QLabel;
import com.trolltech.qt.gui.QMainWindow;
import com.trolltech.qt.gui.QVBoxLayout;
import com.trolltech.qt.gui.QWidget;
import com.trolltech.qt.gui.QPushButton;
import com.trolltech.qt.gui.QTabWidget;

/**

 * @author development
 */
public class siteReviewer {

    public static void main(String[] args){
      QApplication.initialize(args);
      QTextCodec.setCodecForCStrings(QTextCodec.codecForName("UTF-8"));
      QTextCodec.setCodecForLocale(QTextCodec.codecForName("UTF-8"));

      QMainWindow mainWindow = new QMainWindow();
      /* Set main window */
      mainWindow.setWindowTitle("RSC Site Reviewer");
      mainWindow.setFixedSize(600,800);
      mainWindow.setVisible(true);
      /* Set Layout */
      QVBoxLayout vBoxLayout = new QVBoxLayout();
      vBoxLayout.setContentsMargins(0, 0, 0, 0);
      QWidget mainWidget = new QWidget();
      mainWidget.setFixedSize(600,800);
      mainWidget.setVisible(true);
      mainWidget.setLayout(vBoxLayout);
      mainWindow.setCentralWidget(mainWidget);
      /*  */
      /* Setup tab */
      QTabWidget tabWidget = new QTabWidget(mainWidget);
      tabWidget.setDocumentMode(false);
      QWidget tab = new QWidget();
      tabWidget.addTab(tab, "Tab 1 with lots of words");
      QWidget tab2 = new QWidget();
      tabWidget.addTab(tab2, "Tab 2");

      QPushButton hello = new QPushButton("Quit");
      hello.resize(120, 40);
      hello.show();
      vBoxLayout.addWidget(hello);

      QApplication.execStatic();

    }

}

Here is how I compile from command line:

$ javac -cp qtjambi-4.8.6.jar:qtjambi-native-macosx-gcc-4.8.6.jar siteReviewer.java
$ java -XstartOnFirstThread -cp qtjambi-4.8.6.jar:qtjambi-native-macosx-gcc-4.8.6.jar siteReviewer.java

Works fine and windows pops up with expected components.

However, when compiling same code with NetBeans Maven Project:

--- exec-maven-plugin:3.0.0:exec (default-cli) @ SiteReviewer ---
Error: Unable to initialize main class com.ripplesoftware.sitereviewer.siteReviewerApp
Caused by: java.lang.NoClassDefFoundError: com/trolltech/qt/gui/QLayout
Command execution failed.

Here is the pom.xml file:

I'm confused because I'm not calling a class QLayout, and the code compiles fine from command line. I believe the import statements are OK, because it was preivously complaining about the import com.trolltech.qt was not found.
