Handling whitespaces in Xtext grammar

Question

I have a problem parsing following example instruction from Dockerfile:

RUN exec param1 param2

I tried the following:

gramma dockerFile with org.eclipse.xtext.common.Terminals

Run:
    'RUN ' executable=ID (' ' params+=ID)*

and without the extra ' ', but it shows me this error:

extraneous input ' param1 param2' expecting EOF

How do I handle these whitespaces?
