Installation

> npm i -g jenni

Above installation will give you globally available jen command to intract with Jenkins server.

Migration from v0.2.6 to v1

The v1 has breaking changes. If you're using an old version of Jenni, follow the steps below before upgrading to v1.

step 1: Find the config dir path
> jen c
output: Config path - /home/suresh/.config/jenni-nodejs/config.json

step 2: Manually delete the config directory
> rm -rf /home/suresh/.config/jenni-nodejs

step 3:
> npm update -g jenni@latest

Setup

Each git project will requires separate initialization.

jen init will walk you through to initialize jenni to your project.

Usage

> jen --help

Usage: jen [options] [command]

Jenkins personal assistant

Options:
  -v, --version         output the version number
  -d, --debug           Enable debug mode
  -h, --help            output usage information

Commands:
  init|i                Initialize jen
  status|s              Print branch build status
  open|o                Open jenkins build in browser
  build|b [options]     Trigger a new build
  console|co [options]  Show console output
  config|c [options]    Show or Update repository configuration

Command	Options	Description
jen init | i	-	Initialize jenni to your project.
jen status | s	-	Print branch build history.
jen open | o	Optional build number e.g. jen open <build number>	Open jenkins build in the browser.
jen build | b	--watch | -w Watch the console output after triggering a build. --stage | -s Watch the stage view after triggering a build.	Trigger a new build and optionally watch its console output or stage view. Note it's not possible to view console output, stage view together.
jen console | co	--build | -b View specific build console output. e.g. jen console --build <build id>	By default, this command will print the last build console output. If the job has more than one running builds, then it will prompt the user to select a build to retrieve its console output. Use --build option to view the specific build console output. Refer to this flow chart that explains console command behavior.
jen config | c	--username | -n --token | -t --url | -u --job-name --job-path --job-type e.g. Reconfigure username & token jen config --username <foo> --token <bar>	Overwrite project jenni config. Without any options it will print current config.

Debug

It's basic for the moment, pass -d or --debug to log debug messages. Can also be enabled by setting the environment variable DEBUG_JEN to true. E.g.

> jen status -d

// OR

> DEBUG_JEN=true jen status

Known Limitations

• At the moment Jenni handles only WorkflowJob and WorkflowMultiBranchProject job types. So, if you get the error message Unsupported job type: <job type> please file an issue.

• When initializing Jenni (jen init) currently there is no way to interactively select jobs inside the folders (Issue). As a workaround, Jenni will print jobs up to 3 levels deep. For example

  ├── folder-1
  │   ├── folder-1.1
  │   │   └── job3
  │   └── job2
  └── job1
  
  for the above structure, the output will be:
  
  job1
  folder-1 → job2
  folder-1 → folder-1.1 - job3
  

  So if your job is deeply nested, you should manually configure the job. Follow this guide.

Feedback

I'm no expert Jenkins user 🤫. I'm building this tool while learning Jenkins concepts. I'm really interested in hearing your use cases, insights, and suggestions for improvements.
