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？

Question

How to create RCP project without a workspace and other Eclipse default features?

Each time I create Eclipse RCP project, it runs in separate workspace, shows Package Explorer at left, allows to create projects and so on.

Is it possible to create standalone applications like XMind, which just open files of certain types and contain views of certain types?

UPDATE

For example, there is a Zest sample just inside Eclipse help. It is intended to run under Eclipse, but contains main:

How to compile this? If I put it just into java project, it does not have numerous Eclipse libs. But if I create plugin project, I see no place to insert main method.

Answer 1

To get the absolute minimum RCP code do File / New Project and select Plug-in Project . On the second step of the wizard deselect This plug-in will make contributions to the UI and select Yes for Would you like to create a 3.x rich client application . The final step of the wizard will then have a Headless Hello RCP which creates the absolute minimum code for a RCP.

If you leave This plug-in will make contributions to the UI checked some templates to create RCPs with a view etc. are shown.

The above is for Eclipse 3.x style RCPs, for Eclipse 4 pure e4 RCPs use Eclipse 4 / Eclipse 4 Application Project in New Project wizard.
