Answer 1

这是因为您尚未将SWT库添加到构建路径。请遵循本教程的步骤:

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
