Question

我已遵循本教程：https://eclipsesource.com/blogs/tutorials/getting-started-with-EMF-Forms 现在我试图嵌入我在RCP插件中创建（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：

org.eclipse.core.runtime;bundle-version="[3.9.100,4.0.0)",
org.eclipse.swt;bundle-version="[3.102.1,4.0.0)",

当我运行插件时，我收到此错误...有任何建议吗？如果我使用＆＃34;它可以实现：样本e4应用程序＆＃34;

Answer 1

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

在RCP插件
