Set Git's path from Groovy?

[Giro]

I'm finding that upon installation, Hudson's default git path is just
"git" and needs to be fixed. I'd like to do it via Groovy. I've tried
to find the way to set this value with approaches like:

println
hudson.model.Hudson.instance.pluginManager.getPlugin('git').metaClass.properties
println
hudson.model.Hudson.instance.pluginManager.getPlugin('git').metaClass.methods

...to no avail. Any advice on how to set this value programmatically?
