New Slack Plugin for Jenkins

[Tommy Montingelli]

Hi,

I want to write a Jenkins Plugin in Java that trigger a new build when a slash command is typed in Slack. When this appen, an HTTP POST request is sent at Jenkins URL.

I know that i should extend the Trigger Extension Point and define an inner static class that extends the corresponding descriptor to show this option in the Job Configuration page.

So, I have some questions:

1. How I can listen and manage the requests  made by Slack? What are the classes that do this?
2. How I can run my plugin when this trigger option is checked and stop the execution when this option is not active?
3. There are similar plugins?

Thanks.

Hi Tommy,

you could take a look at the git plugin which uses an UnprotectedRootAction as entry point for post-receive hook.

Thanks Vincent. I tried, but nothing. Git is a very large project and it is hard to understand. Other ideas?

Hi Tommy,

We don't do this with slack... but we do with HipChat. The trick for this was to enable Jenkins Parameterized Remote Trigger[1] and then setup our command in our hipchat bot[2] to make requests on the appropriate URL. It's super simple and flexible.

Cheers,

Ben

Hi Vincent,

I was wrong. With UnprotectedRootAction I've created the plugin. Thanks

Very cool. I have seen people use hubot and scripts to do things like this (but then you have to host hubot somewhere).

Hi Vincent,

I have a class that extends GlobalConfiguration. When I install my plugin in Jenkins and my class is instantiated, the instance is null. If I restart Jenkins, the instance is not null. What should I do to avoid restarting Jenkins after installation of my Plugin?

Thanks

Without seeing your code it will be difficult to answer.
