如何在没有工作空间和其他Eclipse默认功能的情况下创建RCP项目？

每次我创建Eclipse RCP项目时，它都在单独的工作区中运行，在左侧显示Package Explorer，允许创建项目等等。

是否可以创建独立的应用程序（如XMind），它们仅打开某些类型的文件并包含某些类型的视图？

UPDATE

例如，Eclipse帮助中就有一个Zest示例。 它旨在在Eclipse下运行，但主要包含以下内容：

        shell.setLayout(new FillLayout());
        shell.setSize(400, 400);

        Graph g = new Graph(shell, SWT.NONE);
        GraphNode n = new GraphNode(g, SWT.NONE, "Paper");
        GraphNode n2 = new GraphNode(g, SWT.NONE, "Rock");

        new GraphConnection(g, SWT.NONE, n, n2);
        new GraphConnection(g, SWT.NONE, n2, n3);
        new GraphConnection(g, SWT.NONE, n3, n);
        g.setLayoutAlgorithm(new SpringLayoutAlgorithm(LayoutStyles.NO_LAYOUT_NODE_RESIZING), true);

        shell.open();
        while (!shell.isDisposed()) {
            while (!d.readAndDispatch()) {
                d.sleep();
            }
        }
    }
 }

如何编译呢？ 如果仅将其放入Java项目中，则其中没有许多Eclipse库。 但是，如果我创建插件项目，则看不到插入main方法的地方。

Answer 1

要获取绝对最小的RCP代码，请执行File / New Project然后选择Plug-in Project 。 在向导的第二步中，取消选择“ This plug-in will make contributions to the UI并为Would you like to create a 3.x rich client application选择“ Yes Would you like to create a 3.x rich client application 。 然后，向导的最后一步将有一个Headless Hello RCP ，它为Headless Hello RCP创建绝对的最小代码。

如果您离开This plug-in will make contributions to the UI选中This plug-in will make contributions to the UI了一些用于创建带有视图等的RCP的模板。

以上是针对Eclipse 3.x样式的RCP，对于Eclipse 4纯e4 RCP，请在“新建项目”向导中使用Eclipse 4 / Eclipse 4 Application Project 。
