add String Option
Adds an option that will have one string value supplied as a separate argument. Calling this method behaves exactly like calling addStringOption(option, null).
addStringOption("foo") will not produce any arguments.
addStringOption("foo").setValue("bar baz") will produce the command-line
-foo 'bar baz'
Return
an option object to further configure the value
Parameters
command-line option
Adds an option that will have one string value supplied as a separate argument.
addStringOption("foo", "bar baz") will produce the command-line
-foo 'bar baz'
A value of null will make the option not be supplied and can be used to unset an option that previously was set.
The returned option object can also be used to further configure the value.
addStringOption("foo", "bar baz").setValue("bam") will produce the command-line
-foo bam
Return
an option object to further configure the value
Parameters
command-line option
the value to supply or null to suppress the option
