[workflow] - First failing Newbie (dir) steps

[Markus "Shorty" Uckelmann]

Hi all,

I just started to play a bit with the workflow-plugin and got stuck with
dir step. My "awesome" code:

stage 'box'
node ('admins') {
def dir = '7packer-boxes'
sh "mkdir ${dir} || :"
echo "Changing to dir ${dir}"
sh "pwd"
dir("${dir}") {
sh "pwd"
}
}


The build starts, works to the point where the dir step is and then
doesn't do anything. Also it just keeps running and I can't remove the
build[1].

Jenkins: 1.596.3
Workflow: 1.6

Any help would be much appreciated.


[1] With /doDelete I can remove it from the slave but it still exists on
the master. A restart of Jenkins might help.


Cheers, Shorty

Hi,

If you are going to use the workflow plugin, I highly recommend you

watch this Youtube video by Cyrille Le Clerc from Cloudbees:

https://www.youtube.com/watch?v=Welwf1wTU-w

That video is so good, I think it should be, put in the README.md file for the Workflow plugin.

I'm not sure, but I think most of your code is unnecessary, unless you have it there for debugging.

I think this should work, but you might want to change the name of the dir

variable just to not clash with the dir() function:

node ('admins') {

     def mydir = '7packers-boxes'

      dir("${mydir}") {

          sh "pwd"
      }
}

The dir() function should create the directory, and in the block, it internally

does a chdir() to that directory and then executes the code in that block.

Regarding cleaning things up, I filed this bug:
https://issues.jenkins-ci.org/browse/JENKINS-28382 "workflow plugin: no option to Wipe Out Current Workspace".

That bug got marked as a duplicate.  There are definitely issues with respect to cleaning up

workspaces used by the workflow plugin.

Anything that helps.

Jep, it's for debugging.

That did the trick! Stupid me...

Ahh, I didn't even know that "dir" creates directories. I wasn't able
to find the documentation for this function. So I was kind of
stumbling in the dark. Are there docs for functions like dir?

Ok, I see if I can jump on this train too ;)

Thanks a lot mate! I was near desperation since noone answered... ;)

Cheers, Shorty
