Every once in a while, at the beginning of a new project, I start the search for a command-line argument parsing library in Java. This post shows the results of examining the field as of mid 2018. This post serves both as a “which to use” and as a “which have been evaluated, and found wanting” guide.<\/p>\n

\nJCommander v1.71
\nhttp:\/\/jcommander.org\/<\/a>
\nannotation, good documentation, custom parser, validation<\/p>\n
\npicocli v3.3
\nhttp:\/\/picocli.info\/<\/a>
\nannotation, good documentation — documentation looks suspiciously like it is patterned after JCommander<\/p>\n
\nargs4j
\nhttp:\/\/args4j.kohsuke.org\/<\/a>
\nfield-based, annotation-based, unclear if “–long-Name” is supported<\/p>\n
\nhttp:\/\/jewelcli.lexicalscope.com\/<\/a>
\nannotation-based, interface-based but can be instance-based with setters, has short and long names<\/p>\n

\nKey-Value – the opposite of a good library. Many of the libraries below share this same deficiency.<\/p>\n

\nsingle “parse” call with array of options, Key-Value get value where key is the option<\/p>\n

\nlike JArgs, except key is “String”, not option object<\/p>\n
\nhttp:\/\/www.cs.ubc.ca\/~lloyd\/java\/argparser.html<\/a>
\ncreate individual options, where options are “holders”, parse() into the holders<\/p>\n
