This is a very small example where we define a command with a class named "HelloCommand".
The easiest way to define a command is by using the @CommandDefinition annotation where you specify
the command name and description. In addition, an Æsh command need to implement the org.aesh.command.Command
interface.
The org.aesh.command.Command interface provides the execute method which is called by Æsh when that specific
command is "executed".
To compile and run you need
- JDK 8 or later
- Apache Maven
3.5.+
Launch the Maven build with:
mvn install
For simplicity we use the Maven shade plugin to package all the dependencies into on jar, to run:
java -jar target/getting-started-0.1.jar
To execute the "hello" command, type "hello". Notice that we use the builtin exit command to have a simple way to exit the CLI.
