How to configure Maven Installation via Groovy

[Kenneth Baltrinic]

I am trying to build a chef recipe to deploy/manage our Jenkins instances.  Things are going reasonably well but the ops-code Jenkin cookbook only provides some basic configuration recipes. It does give you a resource by which to run groovy scripts though and with that and the help of a few blogs I have gotten some basic stuff set up.  However, now now I am trying to do something quite simple in the UI but am stumped about how to do this with a groovy script: Set up a Maven installation that installs a specific version automatically.

Here is what I think I have figured out so far:

import jenkins.model.*

def inst = Jenkins.getInstance()

def desc = inst.getDescriptor('hudson.tasks.Maven')

def installs = desc.getInstallations()

installs in this case seems to have the list of existing installs, but I cannot figure out how to programatically add an install to it, for instance I would like to add an installation that is named 'mvn-3-0-5' that automatically installs maven v 3.0.5.

Any idea on how I can do this?  Any help will be much appreciated.  Thanks.

Hi Ken,

did you solve that problem eventually?

I installed maven outside of jenkins now and it is available and on the PATH, but still I'd need to add it to Jenkins to make it aware of it.

A groovy script would be nice actually...

Cheers, Torben

Hi,

I am facing the same issue.

Did you solve this problem ?

Do you have tips about that ?

Sincerely yours,

Benoit

Useful for me:

import jenkins.model.*

a=Jenkins.instance.getExtensionList(hudson.tasks.Maven.DescriptorImpl.class)[0];
b=(a.installations as List);
b.add(new hudson.tasks.Maven.MavenInstallation("MAVEN", "/usr/local/maven", []));
a.installations=b
a.save()

auto-installs Maven 3.3.9 for example.

Baptiste,

This is great -- thanks! I had a hard time finding an example that'd auto-install Maven for me.

Best regards,
