args4j defaultを表示させない方法

Last updated at Posted at 2019-11-28

概要

先日args4jを使っていて、以下のような現象に悩まされました。
defaultの部分が自動生成される。

-h (--help)    : print usage message and exit (default: true)
-v (--version) : print version (default: false)

解決策

API仕様を見たところ、withShowDefaultsというメソッドがデフォルトでtrueを返しているようなので、falseを渡してあげます。

ParserProperties parserProps = ParserProperties.defaults().withShowDefaults(false);
-h (--help)    : print usage message and exit 
-v (--version) : print version 

defaultが表示されないようになりました。
