To start the IDE from the command line:
The -data setting is optional; if you don't provide it, the IDE uses the default workspace location. If you do include this setting, the IDE looks for or creates a workspace at the specified location. Note that the path given must not contain spaces and non-standard characters, as explained in Workspace.
For more information about starting the IDE, including advanced execution options for developing or debugging parts of Eclipse itself, see
in the Workbench User Guide.
