推荐答案

这是因为你尚未将SWT库添加到构建路径中。按照教程的步骤进行操作：

This is because you haven't added the SWT library to your buildpath. Follow the steps of the tutorial:

1. 下载SWT库。对于3.1.2版本的eclipse，SWT库可以在
   http://archive.eclipse.org/eclipse/downloads/drops/R-3.1.2-200601181600/index.php
   查找标题为SWT二进制和源的部分。


2. 从主菜单工具栏中选择文件，然后选择导入。这样做将打开导入向导对话框。


3. 现在选择现有项目到工作区并单击下一步按钮。


4. 单击选择存档文件，然后单击浏览按钮。现在找到您在步骤1中下载的SWT存档。


5. 单击完成按钮以完成将SWT项目导入工作区。


6. 创建新的来自File> New Java Project的java项目。


7. 右键单击项目并选择Properties命令打开Properties对话框。


8. 选择Java Build Path后跟Projects选项卡，然后单击Add按钮。


9. 选择org.eclipse.swt项目并单击OK完成将SWT库添加到项目的类路径

1. Download SWT library. For 3.1.2 version of eclipse, SWT library is available at http://archive.eclipse.org/eclipse/downloads/drops/R-3.1.2-200601181600/index.php Look for the section titled SWT Binary and Source.
2. From main menu tool bar, select "File" followed by "Import". Doing so will bring up the "Import wizard" dialog.
3. Now select "Existing Projects into Workspace" and click on "Next" button.
4. Click on "Select archive file" followed by "Browse" button. Now locate the SWT archive that you downloaded in step 1.
5. Click the Finish button to finish importing the SWT project into your workspace.
6. Create new java project from File > New Java Project.
7. Right-click on the project and select the Properties command to open the Properties dialog.
8. Select the Java Build Path followed by Projects tab and click the Add button.
9. Select the org.eclipse.swt project and click OK to finish adding the SWT libraries to your project's classpath
