Hello everyone,

I'm looking for help with writing a groovy script for use with jenkins-cli
that can set the ToolInstallation path for a particular slave and tool.
 In https://wiki.jenkins-ci.org/display/JENKINS/Display+Tools+Location+on...
I see how I can enumerate all the tools and their installations.  However,
not being a Java developer, I'm having trouble figuring out what the
inverse of ToolInstallation.translateFor() might be.

First off, is it possible to set the tool path for a slave from a
cli/groovy script?  If so, can someone point me in the right direction for
how I might set (and save) a new path?

Thanks a lot,
Matt

I'm sorry, but I need a little more explicit direction.  I found the source
for ToolLocationNodeProperty, but the class has no setters, so am I
supposed to create a new instance?  I don't want to add a location, I want
to change the one that's already there, so a new instance doesn't seem like
the right thing to do.

Even if I have a new instance, I have to set that on something, but the
Slave class doesn't seem to have a setter for the properties collection
either, so I'm at loss as to how to get my new instance into the Slave's
property collection.  Also, I don't quite grok the relationship between a
property and a descriptor.  They seem to both point to collections of each
other, and neither has a setter for home so no help there in trying to
figure out which one I'm supposed to be dealing with.

I also found NodeProperty.reconfigure(), but have no idea what a
StaplerRequest is or where I'd get one from, nor do have the JSONObject
that I assume represents the configuration.  Is this the route I should be
heading down?  I think this might actually be intended for use by the web
UI and not CLI/Groovy.  How can I get the JSON for the current
configuration for the slave so I can figure out which part to modify?

What would be most helpful is a block of code (even pseudo-code would help)
outlining what I need to do to set the path to the tool.

Sorry to be such a newbie about this, but there's some connection between
all these types that I'm just not seeing.

Thanks for the help,
Matt
