Issue
In scripted Pipeline, if you allocate a node, then use the dir step to change directory, then allocate a new node on the same agent, the directory your build context will be in is incorrect.
If you have only one agent with the label docker, and it has at least two executor slots, you can reproduce this bug by running the following Pipeline:
node('docker') { stage('test') { sh 'pwd' dir('repo') { sh 'pwd' node('docker') { sh 'pwd' } } } } ---
Running this Pipeline will reproduce the issue during the third call to pwd. That call returns /docker/workspace/test/repo when it should be /docker/workspace/test@2:
Started by user admin [Pipeline] Start of Pipeline [Pipeline] node Running on docker in /docker/workspace/test [Pipeline] { [Pipeline] stage [Pipeline] { (test) [Pipeline] sh + pwd docker/workspace/test [Pipeline] dir Running in /docker/workspace/test/repo [Pipeline] { [Pipeline] sh + pwd /docker/workspace/test/repo [Pipeline] node Running on docker in /docker/workspace/test@2 [Pipeline] { [Pipeline] sh + pwd /docker/workspace/test/repo [Pipeline] } [Pipeline] // node [Pipeline] } [Pipeline] // dir [Pipeline] } [Pipeline] // stage [Pipeline] } [Pipeline] // node [Pipeline] End of Pipeline Finished: SUCCESS ---
