eclipse command line switch to start with project

What is the command line option to start eclipse with a specific project?

I can get the correct workspace using -data.

Within that workspace, I want to have a specific project loaded, similar to the "Go Into" 开发者_开发技巧command.

I don't think there is such an option right now.

Oening a file from the command line has only taken 9 years: bug 4922:
If your Eclipse Helios 3.6 eclipse.ini file contains "--launcher.defaultAction", you can open any file with:

eclipse.exe myFile

But open directly a project is still missing.

See this SO question which contains an Eclipse plugin that only loads specific projects (which are defined in a config file) into the workspace.
