正如前面提到的一个评论(https://github.com/pcj/google-options)是一个很好的开始。

我想补充的一点是:

1)如果您遇到一些解析器反射错误，请尝试使用更新版本的guava。在我的例子中:

maven_jar(
    name = "com_google_guava_guava",
    artifact = "com.google.guava:guava:19.0",
    server = "maven2_server",
)

maven_jar(
    name = "com_github_pcj_google_options",
    artifact = "com.github.pcj:google-options:jar:1.0.0",
    server = "maven2_server",
)

maven_server(
    name = "maven2_server",
    url = "http://central.maven.org/maven2/",
)

2)当运行命令行时:

bazel run path/to/your:project -- --var1 something --var2 something -v something

3)当你需要使用帮助时，只需输入:

bazel run path/to/your:project -- --help

Argparse4j是我发现的最好的。它模仿Python的argparse库，非常方便和强大。

我使用过JOpt，发现它非常方便:http://jopt-simple.sourceforge.net/

首页还提供了一个大约8个备选库的列表，检查它们并选择最适合您的需求。

最近有人向我推荐了基于注释的args4j。我真的很喜欢!

我一直试图维护一个Java CLI解析器列表。

我想向您展示我的实现:ReadyCLI

优点:

for lazy programmers: a very small number of classes to learn, just see the two small examples on the README in the repository and you are already at 90% of learning; just start coding your CLI/Parser without any other knowledge; ReadyCLI allows coding CLIs in the most natural way; it is designed with Developer Experience in mind; it largely uses the Builder design pattern and functional interfaces for Lambda Expressions, to allow a very quick coding; it supports Options, Flags and Sub-Commands; it allows to parse arguments from command-line and to build more complex and interactive CLIs; a CLI can be started on Standard I/O just as easily as on any other I/O interface, such as sockets; it gives great support for documentation of commands.

我开发这个项目是因为我需要新的功能(选项，标志，子命令)，并且可以在我的项目中以最简单的方式使用。
