我已经按照本教程：https://eclipsesource.com/blogs/tutorials/getting-started-with-EMF-Forms，现在我试图在RCP插件中嵌入我创建（视图）的EMF表单。我创建了一个简单的RCP4项目，我修改了SamplePart类，如下所示：
public class SamplePart {
private EObject getDummyEObject() {
final EClass eClass = MyPackage.eINSTANCE.getMyModelClass();
return EcoreUtil.create(eClass);
}
@PostConstruct
public void createComposite(Composite parent) {
final EObject dummyObject = getDummyEObject();
try {
final Composite content = new Composite(parent, SWT.NONE);
content.setBackground(parent.getDisplay().getSystemColor(SWT.COLOR_WHITE));
content.setLayout(GridLayoutFactory.fillDefaults().margins(10, 10).create());
content.setLayoutData(GridDataFactory.fillDefaults().create());
ECPSWTViewRenderer.INSTANCE.render(content, dummyObject);
content.layout();
} catch (final ECPRendererException e) {
e.printStackTrace();
}
parent.layout();
}
}
这是我的依赖项列表：

当我运行插件时，我收到此错误...有任何建议吗？如果我使用“make it happen：sample e4 application”它工作正常

您需要在启动配置中添加org.eclipse.emfforms.setup.base和所有必需的插件
