Picocli: Parser bug: first argument following clustered options is treated as a positional parameter

Created on 9 Nov 2017 · 6Comments · Source: remkop/picocli

I use two boolean options. e.g. -c (compress) -e (encrypt) and one string option e.g. -o (outputFile) .
The i use parameter "1..*" FILE for inputFileNames(String[]).

Usage:
cmd -c -e -o OUTPUTFILE INPUTFILE1 INPUTFILE2 INPUTFILE3 -> work
cmd -ceo OUTPUTFILE INPUTFILE1 INPUTFILE2 INPUTFILE3 -> work
cmd -ce -o OUTPUTFILE INPUTFILE1 INPUTFILE2 INPUTFILE -> failed
will be parsed to:
outputFIle=null
inputFileNames[0]="-o"
inputFileNames[1]="OUTPUTFILE"
inputFileNames[2]="INPUTFILE1"
...
cmd -ce -o=OUTPUTFILE INPUTFILE1 INPUTFILE2 INPUTFILE -> failed
will be parsed to:
outputFIle=null
inputFileNames[0]="-o=OUTPUTFILE"
inputFileNames[1]="INPUTFILE1"
...

I will look at this when I get to a PC. Does this match your class? Please let me know if you use different field types or annotation attributes (other than description).

class Mix {
  @Option(names = “-e”, description = “Encrypt”)
  boolean encrypt;

  @Option(names = “-c”, description = “Compress”)
  boolean compress;

  @Option(names = “-o”, description = “Output file”)
  String outputFile;

  @Parameters(arity = “1..*”, description = “One or more input files”)
  String[] inputFiles;
}
