Alexander Fast created CLI-230:
----------------------------------
Summary: Unable to properly require options
Key: CLI-230
URL: https://issues.apache.org/jira/browse/CLI-230
Project: Commons CLI
Issue Type: Bug
Components: CLI-1.x, Options definition
Affects Versions: 1.2
Environment: windows jdk1.6.0_21
Reporter: Alexander Fast
Having some problems setting options as required. Have I misunderstood the
documentation?
* In test1() the option is required but also supplied, I expect to get no
exceptions.
* In test2() the option is required but *not* supplied, I expect to get an
exception.
{code:java}
public class Testing {
public static void main(String[] args) {
System.out.println("Begin test 1");
test1();
System.out.println("End test 1");
System.out.println("Begin test 2");
test2();
System.out.println("End test 2");
}
private static void test1() {
String[] args = new String[] { "--foo" };
Options options = new Options();
options.addOption("f", "foo", false, "");
options.getRequiredOptions().add(options.getOption("foo"));
GnuParser parser = new GnuParser();
try {
parser.parse(options, args);
} catch (ParseException e) {
// didn't expect to get MissingOptionException here
System.out.println("ERROR: " + e.getMessage());
}
}
private static void test2() {
String[] args = new String[] { };
Options options = new Options();
options.addOption("f", "foo", false, "");
options.getOption("f").setRequired(true);
GnuParser parser = new GnuParser();
try {
parser.parse(options, args);
} catch (ParseException e) {
// expected to get MissingOptionException here
System.out.println("ERROR: " + e.getMessage());
}
}
}
{code}
