Post-build Actions on Jobs executed on slaves

[Paul Wellner Bou]

Good morning,

I have a build job checking out a git repository running on a jenkins slave, which works fine. But I am trying to access the workspace in an Post-build Action plugin, which does not seem to be possible: The Post-build Action is run on the master (at least thats what the System.getenv("HOSTNAME") is telling me.

Is there any way to run the Post-build Actions on the slave?

Thank you and regards

Paul.

Are you referring to an action that implements the Action interface? Or to a post build publisher that derives from Recorder or Publisher? 

The latter one can execute Runnables on a slave, e.g. to read information from the workspace. See FilePath#act for details...

Thank you for the reply.

I am using a Publisher extending Publisher.

This looks promising. I discovered a stackoverflow thread with a bit of code doing  a smiliar thing (http://stackoverflow.com/questions/9279898/can-hudson-slaves-run-plugins).

Whats the difference between launcher.getChannel().call(task); and build.getWorkspace().act(task)? The JavaDoc of the latter looks promising.

What I am wondering now, is which Caller to use. There is a FilePath.FileCallable, where the JavaDoc says "Subtypes would likely want to extend from either {@link MasterToSlaveCallable}* or {@link SlaveToMasterFileCallable}."

I would use MasterToSlaveCallable now, does this work on the master then as well? Or do I have to detect somehow if I am running on a master or a slave?

Thank you very much,

Paul.

Hi,

thanks, seems to work now, with MasterToSlaveCallable, on master and slave as well. I just have to take care that all objects I need are serializable.

Regards

Paul.
