Picocli is a framework for creating Java command line applications with almost zero code.

Packages 
Package Description
picocli
Provides classes and interfaces for the main picocli command line parsing and autocompletion functionality.

Picocli is a framework for creating Java command line applications with almost zero code.

The project contains multiple modules, but most applications only need a few of them. The table below shows the JPMS module name and the Maven coordinates for all modules in the project.

Picocli project modules: JPMS module name and their Maven coordinates
JPMS module name Maven coordinates (without version)
info.picocli info.picocli:picocli
info.picocli.codegen info.picocli:picocli-codegen
info.picocli.groovy info.picocli:picocli-groovy
info.picocli.shell.jline2 info.picocli:picocli-shell-jline2
info.picocli.shell.jline3 info.picocli:picocli-shell-jline3
info.picocli.spring.boot info.picocli:picocli-spring-boot-starter

Most application will only need the main picocli module, but we recommend also configuring the picocli-codegen module as an annotation processor for your project. This provides compile-time error checking and generates GraalVM configuration files under META-INF/native-image/picocli-generated/$project during compilation, to be included in the application jar. This in turn facilitates converting your command line application to a native image.

The picocli-groovy module allows Groovy scripts to use picocli annotations for even more compact code.

The picocli-shell-jline2 and picocli-shell-jline3 modules are of interest to applications that want to provide an interactive shell-like console.

The picocli-spring-boot-starter module provides Spring integration. Particularly, it allows for @Autowired or @javax.inject-annotated program elements in picocli components (commands, subcommands, type converters, default providers, etc.) to be injected with values from Spring's Application Context.
