ArgumentBuilder.withMaximum causes parse errors: Unexpeced <value> while
processing options
-------------------------------------------------------------------------------------------
Key: CLI-145
URL: https://issues.apache.org/jira/browse/CLI-145
Project: Commons CLI
Issue Type: Bug
Components: CLI-2.x
Affects Versions: 2.0
Environment: Windows XP
Reporter: David Biesack
With the sample program below, running with the arguments
-a 0 -b 1 2 3 4
causes the error:
Unexpected 3 while processing options
Usage:
[-a <a1> [<a2> ...] -b <b1> <b2> [<b3> [<b4>]]]
options
-a (--a) a [a ...]
-b (--b) b b [b [b]]
I specified .withMinimum(2).withMaximum(4)
The help is correct, but the value '3' is not added as a value.
Note also that if for bOption, if you add two more defaults (uncomment them in
the source)
.withDefault("10000")
.withDefault("1000000")
an error is raised (incorrectly) on the first b value (i.e. 1 instead of 3) :
Unexpected 1 while processing options
Usage:
[-a <a1> [<a2> ...] -b <b1> <b2> [<b3> [<b4>]]]
options
-a (--a) a [a ...]
-b (--b) b b [b [b]]
