Palmer Eldritch created CLI-229:
-----------------------------------
Summary: Missing place holder in required argument
Key: CLI-229
URL: https://issues.apache.org/jira/browse/CLI-229
Project: Commons CLI
Issue Type: Bug
Components: CLI-1.x
Affects Versions: 1.2
Environment: Windows 7 x64, Java 1.7.9
Reporter: Palmer Eldritch
Priority: Minor
Fix For: 1.3
The code below :
{code}
@SuppressWarnings("static-access")
public class CliArgBug {
private static final Options OPTIONS = new Options();
static {
// FIXME : bug ? usage prints --seq1 --seq2 <arg> - notice <arg>
// missing in seq1 - corrected by adding .withArgName("file1")
OPTIONS.addOption(OptionBuilder
.withLongOpt("seq1")
.withDescription(
"REQUIRED : the file containing
sequence 1")
.hasArg().isRequired().create());
OPTIONS.addOption(OptionBuilder
.withLongOpt("seq2")
.withDescription(
"REQUIRED : the file containing
sequence 2")
.hasArg().isRequired().create());
}
public static void main(String[] args) {
HelpFormatter formatter = new HelpFormatter();
formatter.printHelp("Notice <arg> is missing in seq1", OPTIONS,
true);
}
}
{code}
Produces :
{code}
usage: Notice <arg> is missing in seq1 --seq1 --seq2 <arg>
--seq1 REQUIRED : the file containing sequence
--seq2 <arg> REQUIRED : the file containing sequence 2
{code}
Also I was not able to find any info on where this placeholder <arg> is defined
- please add this to the javadoc
Thanks
