Right click on the project, choose 'Properties'. In 'Java Build path', go to the 'Libraries' tab, and click on 'add JARs' to include jar of the workspace in the build path of your Java project.
右键单击项目，选择“属性”。在“Java 构建路径”中，转到“库”选项卡，然后单击“添加 JAR”以在 Java 项目的构建路径中包含工作区的 jar。

If you are using an osgi run configuration, Run -> Run Configurations... Select you laucher and click on the Bundles tab. Filter with org.eclipse.swt and make sure that the org.eclipse.swt and org.eclipse.swt.[arch].[version].jar are checked.
如果您使用的是 osgi 运行配置，请运行 -> 运行配置...选择您的 laucher 并单击 Bundles 选项卡。用 org.eclipse.swt 过滤并确保 org.eclipse.swt 和 org.eclipse.swt.[arch].[version].jar 被选中。
This drove me nuts until I did this simple thing. If you validate bundles without having checked these you'll get a "No Problems" dialog but you'll get this error at run time
这让我发疯，直到我做了这个简单的事情。如果你在没有检查这些的情况下验证包，你会得到一个“没有问题”对话框，但你会在运行时收到这个错误
