问题描述
我有一个在GUI设计师的帮助下创建的项目。
这是主要表格的代码。
I have a project created with help of GUI designer. Here is code of main form.
public class MainForm {
MainForm() {
directLineOkButton.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent arg0) {
//some action
}
}
});
crossLineOkButton.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent arg0) {
//some action
});
clearButton.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent arg0) {
//some action
});
cancelButton.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent arg0) {
//some action
});
saveButton.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent arg0) {
//some action
});
}
public JPanel getMainPanel() {
return mainPanel;
}
private void createUIComponents() {
drawingPanel = new DrawingPanel();
}
private JPanel mainPanel;
private JComboBox directDirectionCombobox;
private JButton directLineOkButton;
private JButton crossLineOkButton;
private JComboBox crossLineComboBox;
private JTextField crossLineSizeValue;
private JButton clearButton;
private JLabel directLineLabel;
private JPanel directLinePanel;
private JLabel crossLineLabel;
private JPanel crossLinePanel;
private JPanel okClearButtonPanel;
private JTextField directLineSizeValue;
private JButton saveButton;
private JPanel drawingPanel;
private JButton cancelButton;
}
一切正常。 jar文件生成正常，这里是pom.xml的代码
It works fine. Jar file generates fine, here code of pom.xml
<?xml version="1.0" encoding="UTF-8"?>

但是当我尝试运行jar文件时出现错误。
But when I try to run jar file there is a mistake.
Exception in thread "main" java.lang.NullPointerException
at MainForm.<init>(MainForm.java:14)
at Main.main(Main.java:13)
它显示错误位于directLineOkButton监听器的行被建造。我创建了如下所述的监听器：
http://www.jetbrains.com/idea /training/demos/GUI_Designer/GUI_Designer.html
在构造函数中使用cmd + o。
以下是xml表格的代码：
It show that mistake is at the line where directLineOkButton listener is created. I create listener like said here: http://www.jetbrains.com/idea/training/demos/GUI_Designer/GUI_Designer.html in constructor using cmd+o. Here is code of xml of form:

推荐答案
您必须包含 ideauidesigner- maven-plugin ：
<build>
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>ideauidesigner-maven-plugin</artifactId>
<version>1.0-beta-1</version>
<executions>
<execution>
<goals>
<goal>javac2</goal>
</goals>
</execution>
</executions>
<configuration>
<fork>true</fork>
<debug>true</debug>
<failOnError>true</failOnError>
</configuration>
</plugin>
</plugins>
</build>
并且可选 - 如果您使用 GridLayoutManager 或 JGoodies - 还包括 forms_rt 作为依赖：
and optionally - if you use GridLayoutManager or JGoodies - include also forms_rt as dependency:
<dependency>
<groupId>com.intellij</groupId>
<artifactId>forms_rt</artifactId>
<version>7.0.3</version>
</dependency>
