Cloud slave never provisioned (sometimes)

[thomas . suckow]

 

I am trying to track down an issue where a cloud slave is never provisioned 
for a job that is scheduled. The annoying part is that it doesn't always 
happen, I would estimate about 1 in 4 times. I am specifically using the 
docker-plugin and the job is triggered by gerrit. Only one job appears to 
be affected and there are many other similar jobs that are similar (docker 
slave with a gerrit trigger)

I have added more debug logging to the docker-plugin to monitor how 
provisioning occurs. Sure enough provision() is never called, though 
canProvision is and returns true for the label expression.


I am not sure how I can inspect more into how Jenkins provisions cloud 
slaves and figure out why it never does. If another job comes along, it 
will provision for that job and leave this one.


Log snippet:

Any thoughts appreciated,

Thomas

Re: BuildWrapper before SCM checkout?

This is a good reference, thank you!

I looked at the BuildWrapper API, but somehow read right past 
preCheckout. Maybe I should clean my glasses ;)

Let me know if that works for you.

I am new to plugin development and am mostly looking to enhance an
existing one.

The SSH-Agent plugin is a BuildWrapper which unfortunately means
it runs after all the code is checked out from scm.

Is there another task type that would occur before scm checkout so
that the ssh-agent could be setup and used to checkout/clone the code?
