Description
When running the tee command on parallel stages the console output becomes garbled. The stage name is displayed directly over other stage names, and output is mangled together.
pipeline {
agent any
stages {
stage('stage') {
steps {
script {
parallel ((1..20).collect{it}.collectEntries {stageNumber ->
["$stageNumber": {
node('master') {
stage("$stageNumber") {
tee('output.log') {
sh("for i in 1 2 3 4 5; do sleep 1; echo $stageNumber \$i; done")
}
}
}
}]
})
}
}
}
}
}
Will produce console output such as:
...
+ for i in 1 23 3 4 5
+ 4s l5e
e+p 3s
leep 3
++ e cehcoh o5 62
25
62 2+ +f ofro ri ii ni n1 12 23 34 455
...
However, this behaves nominally if the tee block does not call sh:
[1, 2, 3, 4, 5].each {
sleep 1
echo "$stageNumber $it "
}
For a POSIX compliant workaround, this seems to work for me:
sh(returnStatus: true, script: """#!/bin/sh { { { { (set -xe; $script) 2>&1; echo \$? >&3; } | tee $output >&4; } 3>&1; } | { read xs; exit \$xs; } } 4>&1 """)See:

But I additionally wrapped the script with an internal set -xe, and redirected the script's stderr to stdout.
