Getting Started with the Command-Line Interface (CLI)
In the next chapter, we look at various development environments, including the command-line interface (CLI). Let's take a quick look at the CLI now just to get acquainted with it. As we saw, the CLI is a module retrieved from a remote module repository. There are many commands available, but don't let this scare you. The CLI is very helpful. To get a list of available commands, type the following:
zero help
The results of typing this into the command line can be seen in Listing 1.9.
Listing 1.9. Results of the "Zero Help" Command
Usage: zero [main-opts] <task> [task-args]
main-opts:
-d enable minimal logging
-v enable all logging
-l=<file> use the given file to output log to
compile Compiles all Java source files under the module's
/java directory.
create Creates a new module in the current directory.
help Prints the documentation for the given command.
modulegroup Manage modulegroups.
package Packages the module as a zip file.
publish Publish the module to your local repository.
repository Manage repositories.
resolve Determine the module's dependencies.
rollback Reverts the effects of the last resolve or update.
search Finds and prints all matching modules in the reposi-
tory.
switch Switch the module group.
update Resolves a module to its latest dependencies.
version Displays version information
As you can see, there are a bunch of available commands. Each command may have arguments that it can be given, but again the command line is very helpful. You need only to type the following to get help on a particular command:
zero help <command>
For example, if we use zero help search, we get the results shown in Listing 1.10.
Listing 1.10. Results of "Zero Help Search" in the CLI
Usage: zero search <org:module[:revision]> [-remote] [-json] The command uses the current module group to find in the local re- pository for a module that matches the given <org:module:revision> value and prints its search results. If no module name is given, the command will print information about all available modules. You can also use the -remote option to tell the command to search the remote repository instead of the local one. If the -json option is used the report is formatted as a JSON docu- ment. The return codes for this command are: 0 - success 1 - command failed
The search command enables you to search for modules in the repository. There are commands to create new IBM WebSphere sMash applications, start and stop applications, package applications, and many more. Spend some time familiarizing yourself with the commands, and we'll take another look at the CLI in the next chapter.
