Question

同一个 Java 类将从命令行编译，但不会从 NetBeans 编译。这是 .java 文件内容：

这是我从命令行编译的方法：

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();

    }

}

工作正常，窗口弹出预期组件。

但是，当使用 NetBeans Maven 项目编译相同的代码时：

$ 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

这里是 pom.xml 文件：

--- 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.

我很困惑，因为我没有调用类 <?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.ripplesoftware</groupId> <artifactId>SiteReviewer</artifactId> <version>1.0-SNAPSHOT</version> <packaging>jar</packaging> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <maven.compiler.source>16</maven.compiler.source> <maven.compiler.target>16</maven.compiler.target> </properties> <dependencies> <dependency> <groupId>com.trolltech.qt</groupId> <artifactId>qtjambi</artifactId> <version>4.8.6</version> <scope>system</scope> <systemPath>/Users/${USER}/.m2/dependencies/qtjambi-4.8.6.jar</systemPath> </dependency> <dependency> <groupId>com.trolltech.qt</groupId> <artifactId>qtjambi-native-macosx-gcc</artifactId> <version>4.8.6</version> <scope>system</scope> <systemPath>/Users/${USER}/.m2/dependencies/qtjambi-native-macosx-gcc-4.8.6.jar</systemPath> </dependency> </dependencies> </project>，并且代码从命令行编译得很好。我相信导入语句没问题，因为它之前抱怨没有找到 QLayout。
