Starting Eclipse w/ Specific Workspace

From http://help.eclipse.org/help21/topic/org.eclipse.platform.doc.user/tasks/running_eclipse.htm:

Use the following command-line argument:

-data your_workspace_location

For example,

-data c:\users\robert\myworkspace

you can also use UNIX-style relative path names such as

-data ../workspace

even under Windows, in case something doesnt like colons or backslashes in parameters, like Jumplist Launcher

With the -data switch

Setting a specific location for the workspace with -data

To use the -data command line argument, simply add -data your_workspace_location (for example, -data c:\users\robert\myworkspace) to the Target field in the shortcut properties, or include it explicitly on your command line.
